It is true that temperature greatly affects the pressure of a tennis ball; temperature can increase and reduce pressure of a tennis ball, depending on the heat added or taken away; this would benefit people designing objects to absorb shock. Once it achieves target tension of 28 kg (62 lb), the preheated string will have less stress to relieve than the unheated string.

Stiffness decreases with an increase in temperature and increases with a decrease in temperature. The deltoids and pectorals major are used to flex the shoulder. Tennis serve is the shot that starts off the point. The regression Graphs 3, 4 show R squared values considerably higher than any of the time regression models. If we graph post-relaxation stiffness vs temperature for each string, we begin to see some patterns. In general, players can compensate by adjusting playing style as well as making technical tweaks to their rackets and stringing configurations. Will the Temperature of a Tennis Ball Affect the way it bounces? The string ends extended past the end of the tube and were clamped. Hockey Stick Contribution to Puck Speed in Slap Shots, Introduction to the Physics of Hockey Sticks. A further study should be completed to see if anything else effects the balls differently to try and determine what makes the balls different. In order for maximum force to be generated, a tennis player needs a good stable base from where they can begin the movement. After doing this activity, I observed that as temperature decreases so does the pressure. Temperature has a significant positive relationship with the bounce height of tennis balls. (Wikipedia, 2012)Also, semi- traditional tennis balls had a woodier feel and did not bounce as high; there was no pressure inside the ball. Thermometer Temperature Cubic ANOVA, Table 14: Ball 2 vs. Here is another table that shows the exact height in which the ball bounced. Analyze the data, and make a conclusion stating if the temperature of a tennis ball affects how high it bounces. You can also change how a ball bounces by changing its temperature. With an increase in the temperature, the gas molecules within the tennis ball start to expand. Results for Setup #1 tension loss vs timing of heat application. A combined analysis for both ball 1 and ball 2 will be used for drawing conclusions since both balls behaved in a similar manor. Throughout this essay, I will not only explain what each of Newtons three laws mean, but provide a real life example of how it could relate to the game of bocce ball. By far the cubic fit is the best out of the three regression models analyzed but the R squared values are all well below 0.9 which is what would be needed as a minimum to make the models good predictors for future trials. Retrieved 8 24, 2012, from LIVESTRONG: http://www.livestrong.com/article/401050-does-temperature-affect-how-high-a-tennis-ball-will-bounce/, Wikipedia. Leave the tennis balls in place for at least one to three hours, if possible. NOTE: IEEE WAS NOT AVAILABLE FOR CITATIONS, SUBMITTED TO SABIO ACADEMY TO MEET THE REQUIREMENTS OF THE SR 90 JUNIOR RESEARCH COURSE AT SABIO ACADEMY. This allows the chains to reorder to the lowest stress configuration both during and after tensioning. Retrieved 8 24, 2012, from ITF Tennis: http://www.itftennis.com/technical/equipment/balls/history.asp, Sheehan, K. (2011, March 11). Time was analyzed next in Table 3, 4. Drop the ball from that height, and measure how high it bounced. When the temperature increases, the gas molecules inside the tennis ball expand. Hold the meter stick vertically with one end on the ground. Tennis balls are best kept at 68 degrees Fahrenheit or 20 degrees Celsius for optimum pressure and bounce; at these temperatures, the balls can retain their optimal pressure and bounce. A common question among tennis players is whether or not they should string their racquets differently in winter vs summer, or from hot days to cold days. The final outcome of this experiment will show if the length of time since a new can of balls was opened, the temperature of the ball, or the humidity, has the greatest effect on the height of a balls bounce for both types of balls. The data from this experiment will show their differences. Figure 8 Closeup of stiffness vs temperature for each nylon and polyester string. These acquired values show that the line is a good predictor of future points and where they will fall. Fourteen strings were tested: 1 gut, 1 kevlar, 7 nylon, 5 polyester. For the sake of our experiment today, you will need to have a concrete floor or other hard surfaces that will be used to perform the bouncing test. Leave 2 out for 10 mins so they can come to room temperature. Page #10 . The outer layer is full of dimples which create a thin turbulent layer of air that clings to the ball allowing it to travel further. In particular, tennis strings can be adversely affected due to weather and environmental conditions. This means that the tennis ball becomes dead after ten games, and after that, it is in a bricked state, and for this reason, it can not be used anymore. Continue the same procedure until all balls have been tested. Whenever this ball falls to the ground, its air expands, causing the ball to bounce back. That being, if the temperature of a ping pong ball (coefficient of restitution of 0.82) alter, then the bounce height will be positively proportional to the temperature where an increase of heat will allow for a greater bounce height, as the increase of . That is, it is more susceptible to wear in unfavorable conditions. Upon conclusion, I am to determine why resistance was limited during the activity. Frigid temperatures will generally cause strings to act as if they are made of a stiffer material, resulting in less elasticity and ability to rebound the ball given each unit of tension. Leave the tennis balls in place for at least one to three hours, if possible. While high temperature and high humidity are technically different measures, they often occur together. (Borlings, 2011) From the 1920s, the process of making a tennis ball was based on the clover-leaf principlewhere a sheet of rubber was shaped into a three-leaf clover. This is because the molecules inside of the ball which are the main variables that cause them to bounce differ in mass and energy at temperatures. Method: 1. different types of ball material: rubber (lawn-tennis ball, super ball, soccer ball and squash ball) and plastic (table-tennis ball) at room temperature. The difference in stiffness between temperatures for each string was greater for the nylon strings. This is not the expected result. (Incorporation, 2011)The first rubber tennis balls were made out of pure rubber, and their properties were increased by stitching flannel on to the core. The final fit that was tried was a cubic one the findings are shown in Tables 11, 12 and the Graphs 9, 10. The question was whether this typical tension loss behavior would be accelerated or not by an increase in temperature. Repeat for each of the hot and cold balls and record the readings for each ball. The result is more viscous behavior with chains slipping, sliding, and reorienting relative to each other. Here, weve detailed some of the main ways in which the weather and environment can influence not only the way tennis strings react and work but also the match overall. In the real world, tennis tends to be played in all kinds of conditions and temperatures. Does Temperature Affect How High a Tennis Ball Will Bounce? Exploratorium: That's The Way The Ball Bounces. Gas molecules are generally unorganized; they easily slide around and over one another to fill up any space they occupy. Analysis The heated tennis balls bounced the highest because as the temperature rose, the molecules expanded and exerted more pressure when the ball bounced The experiment illustrated the perfect gas law, because it showed that when the temperature rose, so did the pressure The data for each set of tennis balls had a range of 15 . But if the tennis ball is heated it will have the opposite affect. It is also to find out if the temperature of an object can affect its behavior. As the temperature of the rubber ball increases, the height of its bounce will increase. Two variables will be omitted in the study, how much the ball is played with and different court surfaces. Molecules of a gas can effortlessly expand and contract. While a temperature change in one direction has a high-bouncing effect, a temperature change in the other direction reduces the balls bouncing abilities. The results are not quite as tidy and a bit unexpected. Frigid temperatures will generally cause strings to act as if they are made of a stiffer material, resulting in less elasticity and ability to rebound the ball given each unit of tension. She works in a neonatal intensive care unit (NICU) and her previous nursing experience includes geriatrics, pulmonary disorders and home health care. Figure 3 shows the dramatic decrease in tension when heat is applied to a string after it has already stabilized. Photos of the investigation being conducted The target temperatures were achieved just prior to tensioning and maintained during the tensioning and relaxation phases. Does Air Pressure Affect the Bounce of a Basketball? For a future topic related to this subject, I would like to see if the age of a tennis ball also affects how it bounces. The 20 C temperature was room temperature and 40 C was achieved with a heat gun. Retrieved 8 24, 2012, from LIVESTRONG: http://www.livestrong.com/article/398740-temperatures-tennis-balls/, Incorporation, I. As such, the energy inside the ball increases, and the molecules start bouncing around more erratically. Crawford Lindsey, Tennis Warehouse, San Luis Obispo, CA. Create a free website or blog at WordPress.com. A string was inserted inside clear perspex tube with two open ends and through a small hole in a rubber stopper at each end of the tube. As shown in Figure 10, elongation is proportional to temperature. Drop ball and mark where the lowest part of the ball is after the first bounce. Notebook The experiments The p-value for both was zero showing that there is a significant relationship between the time a can of balls was open and the bounce height. Gather 15 to 20 tennis balls and a measuring tape. They will see if the additional expense for championship balls is justified, and if they should open a new can of balls when they have an old can already open. Standing on the strong chair will have a better height to drop the balls from, which means that the results will be more accurate. the serves comes in five main types of which includes; cannonball or flat serve, topspin-slice serve, slice serve, American twist serve and the topspin serve. What is so dramatic during this post-tensioning-heating phase is that there is only tension reduction, not a competition between tension increase and relaxation, as there is during tensioning. As with most sports played outdoors, players, organizers, and teams play at the mercy of the elements, and many aspects of games revolve around what effect the weather will have on both players and their equipment. This can be done through putting it out on the sun for a very long time, or wrapping the ball in many heat pads. Do not forget to note the temperature of each ball before bouncing it off the ground to ensure that you get the best kind of results. This type of heating has a permanent effect. Does it matter when the string is exposed to a temperature extreme before, during, or after tensioning? The ball will not bounce much in the winter, which means that the players will not be as active on the field as they are during the summer season. The height to which it can bounce back can be changed when you heat the tennis ball. Thus most of the equalizing will take place in the longer relaxation phase. The green represents the felt on the ball, and the black represents the hollow core. (Sheehan, 2011)However, if one lets the ball continue to bounce, it will bounce less high each time until it eventually just sits on the ground. As such, the heated ball will tend to have a higher bounce than the colder ball. Easy Experiment. Using balls that are all new means that your experiment will be more consistent, and as such, you will be able to get the best kind of results. Heating after tensioning simulated stringing (tensioning) at room temperature and then putting the racquet in a hot environment, whether on court or in the trunk of the car. This means that the pressure is optimal for performance on the field. As such, gas molecules can easily expand or contract. The ruler was placed firmly on the ground at 90 such that it stood as vertically as possible. Strong chair Figure 10 breaks out elongation vs temperature by string in each material group. Create a graph or a table showing how high the balls bounce in different temperatures. It is the other way around for polyester the 20 string loses more tension than the 40 string. Setup #2 Stiffness, Elongation, and Tension vs Temperature. The player may also feel stiffer on a cold day. Time out of the can does pose a significant relationship, although that relationship can not be proven with the data from this experiment. Electrical tape Thus, each string at 0 C was stiffest, followed by 20 C and 40 C (Figure 7). Figure 6 Composite view of tension loss by string and temperature history (indexed in order of tension loss at room temperature of 20 C). Then, analyze the information. Place the tape measurer against the edge of a wall using the bluetack 3. What players feel when hitting in various temperature conditions is the combined effect. This is the table showing the heights in which the ball bounced. The colder air will also have molecules closer together, and they will also tend to be more inert in the sense that they will not be able to move around much. Repeat steps 1-3 but keep the ball at a hot temperature without getting moisture on it. The impact duration was between 65 and 71 ms. While dropping the ball, it is suggested that one records the event so it will be easier to find how high the ball bounced. The balls need to have the right temperature and air pressure inside in order to work best. Strings were stretched until they reached a tension of 28 kg (about 62 lb). However, at 63, The learning quesiton that I chose required me to perform atleast one exercise for each major muscle group on a stability ball. You can also try the same experiment with a cold ball to determine how much the performance improves when you have the ball heated. Rather, it is something that naturally happens. The scientific equation for determining the pressure of gas is p=rRT, where p is the pressure, r is the density, R is a constant specific to the gas and T is temperature. It uses a lot of muscle memory. Its also worth noting some of the less short-term effects on racket stringing. Setup #2 Stiffness, Elongation, and Tension vs Temperature. According to Aleks Szymanski from tennisletics.com, tennis balls are hollow and contain air that expands in the event of high temperatures, causing the balls to bounce more freely. The movement of the air and the squishing inwards when the ball has been dropped cause the ball to push out again, which is the reason for the bouncing movement. The differences, however, were not great. The greatest effect observed in this experiment was that exposing a string to high temperatures after post-tensioning stabilization/relaxation has occurred (as in leaving the racquet in the car during hot weather) produces the greatest decrease in tension. The bladders are usually made of rubber or rubber like things. Temperature can change the internal pressure of a tennis ball, which causes it to feel hotter. To do this, place them in the ice chest with ice. Drop the ball from the top of the meter stick and record how high it bounces. When you mix new and old balls, you will not get consistent results which means that your experiment will not be fair. (Incorporation, 2011)It was also composed of a mixture that seemed like putty and human hair. This is expected. Video footage will also be utilised to measure the bounce correctly by watching the film in slow motion. The stiffness, k, is calculated as k = dF/dx, where dF is the increase in the force when elongation increases by dx. Baseballs have less bounce than tennis balls or golf balls. (Borlings, 2011)The game is outdated and is not played anymore. 1b Heat after tensioning and stabilization. America seemed very separated from the game until a sweep of popularity in California in 1989. Ever felt that muggy feeling when it is particularly humid outside? Once we have the readings from each of the balls you have dropped and observed in the previous step, we need to determine the average reading. Tests with this apparatus were conducted at 20 C and 40 C. 20 C was room temperature with air conditioning. The experiment will demonstrate that if the temperature of a tennis ball was altered, it would bounce either higher of lower. Sheet3. Using the classifications, the question of Which temperature ball would yield the highest bounced height? would be answered. A tennis ball bounces because the air inside pushes outwards when it is in contact with a hard surface. Only string number 7 does not fit the pattern of stiffness being inversely related to temperature. Conclusion. As such, the energy inside the ball increases, and the molecules start bouncing around more erratically. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); Enter your email address to follow this blog and receive notifications of new posts by email. This allows more elongation at lower stresses than occur at lower temperatures. Record the temperature on the thermometer. When a tennis ball is compressed, its internal air pressure is boosted. A typical result is shown in Figure 5 at 20 C. Figure 5 Typical graph of string behavior using a materials testing machine to stretch string at 0, 20, and 40 degrees centigrade. For nylon, the 40 string loses more tension than the 20 string. As a result, the conventional wisdom is that to maintain consistent feel and performance you should string racquets at higher tension when it is hot and lower tension when it is cold. The first setup (Figure 1) was used to measure tension vs time for strings with different temperature exposure histories. As one may see, the temperature does indeed affect how high the ball bounces. Copyright 2023 Elite Tennis Guide | All Rights Reserved. In the study, they considered strings of different materials under different temperatures. Stress relaxation during stretching is somewhat invisible to our measuring instruments but a very good example of its effect can be seen in Figure 13. I thank Dr. Choi for teaching me how to do this assignment and my parents for buying tennis balls for me. For instance, at 70 degrees the temperatures were both 12.5 psi because that was the initial pressure of course. After the ball hits the floor the ball gains motion that is. On the other hand, a temperature decrease causes the gas molecules to contract and move around more sluggishly. As such, tension loss is just a partial and often misleading participant in determining string stiffness the most important parameter in string performance. How does temperature affect the bounce of a tennis ball? When you have heated the balls, you will have provided them more energy to move about, and as such, they will be able to bounce to higher heights when they are dropped to the ground. Hi I am Andrew. Pen. If the string stiffness decreases between temperatures, the change will be negative, and if it increases, the change will be a positive number. Purpose The purpose of this project is to determine how tennis balls are affected by different temperature conditions. Your email address will not be published. String materials vary in terms of their durability, given extreme weather conditions. You need to be able to move quickly and effectively to reach the ball quickly and hit it. An increase in R squared to values of 0.974 and 0.957 were seen and suggests that the quadratic fit is even better than the linear one. This increases the time it takes to achieve the target tension. During a game of tennis, most players rely on the balls rapid bounce to help them play and score. Method 1) 2 rubber balls were left sitting at room temperature, and 1.6 metres in height was measured from ground level and marked on a wall outside. Stiffness is the most important property of strings. Players often wonder how storing their racquets in the trunk of their car during extreme hot or cold weather would influence tension and performance? Why Is String Stiffness So Important To Power? Figure 12 zooms in on tension loss behavior for each nylon and polyester string. (Incorporation, 2011)In the late 1920s, tennis balls became pressurized. When a ball drops gravity pulls it down to the ground. An experiment was performed to determine the effect of temperature on the stiffness, elongation, tension loss and maintenance of tennis strings. One may also use a heat dish to do this. Racquetball is played on a rectangular indoor court with four side walls and a ceiling. Researchers Crawford Lindsley and Rod Cross performed an in-depth study exploring the effect of temperature on string tension and stiffness. The result differed from expectation in that, except for 4 strings, the 40 preheat scenario had the least loss of tension. From the things they can controllike diet, rest, and conditioning, to the things that are relatively less predictablelike weather conditions and temperature, good players are continually considering all eventualities. (Borlings, 2011)However, in 1470, Louis XI of Franceforbade the filling of tennis balls and said that they should be filled with high-quality leather. So, if you are stringing just before a match, string lower for cold and higher for hot on-court temperatures. Two different types of balls, Penn Championship and Non-Championship will be compared. The use of different kinds of balls will help you determine whether the temperature is the only variable causing your results to be varied. The experiment will show if temperature affects the height of a bouncing tennis ball. Tennis balls were first made in the early 1300s. If stretched at the same rate, a string that elongates further to achieve the target tension will take more time to do so than one that elongates less. Do you know what mechanics are really behind the outer layer? The scientific equation for determining the pressure of gas is p=rRT, where p is the pressure, r is the density, R is a constant specific to the gas and T is temperature. Now the equilibrium between the tension and the bonds is broken. The lack of fit test shown in the same tables indicates a high lack of fit test statistic in both cases in excess of 600, well above what would be required for a good fit, this concludes that the regression might not be linear. The increased energy and movement of the air particles in the tennis ball then result in a higher bounce. It is common knowledge that most strings lose a large percentage of tension with time and play. The main. Thus it takes quick reaction time and reflexes to play at higher levels. As the tennis ball returns to its normal shape, the gas inside the ball acts as a spring and causes the ball to bounce into the air. Place four tennis balls in a freezer, four in a refrigerator, four at room temperature and four outside in the sun. This increased accessibility to insights both on and off the court will help tennis players everywhere. When a tennis balls temperature changes, the balls gas-filled core undergoes an interesting reaction. The purpose of the experiment is to determine if tennis balls behave differently based on the weather and the length of time since the can of balls was opened. A good example of this would be, when designing buildings to survive in areas where earthquakes happen frequently. How Do Different Surfaces Effect The Bounce Of A Tennis Ball? Confirming beliefs and behaviors is as important, if not as sexy, as exposing the myths and follies of our concepts. When the temperature increases, the gas molecules inside the tennis ball expand. Figure 12 Tension vs time for a string tensioned to 28 kg for several different time intervals prior to clamping. Secondly, testing our experiment with two different balls of the same type to ensure that they reflect the same amount of result. Tension stabilization continues forever, but at a continually decreasing pace. (Harriman, 2012). Then they would be dropped from a table, and the height would be measured. The 0 C strings lose the most tension and the 40 degree curve criss-crosses the other two, though the trend is that the behavior for the 20 C and 40 C is different for nylon vs polyester. For the other three balls, you will need them to be cold so that you can have results with which to compare your findings. Temperature Cubic ANOVA.
