Warm Versus Cold Tennis Ball (Page 3)

Dr. Jani Macari Pallis, our project's principal investigator decided on these questions:

Problem : Does the temperature of a tennis ball affect its bounce?
How does temperature affect a tennis ball?
How does this affect a game?

Why did she choose these? "In thinking about the experiment I wanted to know which ball bounced higher. Maybe none of them bounce higher? I didn't want to restrict the question to just does a cold ball bounce higher? Or does the hot or warm ball bounce higher."

"Also, I don't just want to know if one of the balls bounces higher. I want to know why it does. That's why I wrote my second question: How does temperature affect a tennis ball?. Does the temperature affect the ball material? Does it affect the air inside the ball?"

"Last I want to know how this can affect a game. Do balls bounce differently based on the temperature at your club, court or tournament? Do hot/cold balls still bounce within the range specified by the ITF (International Tennis Federation)? Maybe the balls bounce differently but it doesn't really affect a game. Maybe the balls would have to be so hot/cold that realistically you couldn't play. That's what I'm interested in finding out!"
