How does air pressure and density of the air inside a tennis ball change in different temperatures?
as temperature increases, the atoms move faster in the tennis ball, increasing air pressure, expanding the ball since the ball is more expanded, the ball will have more bounce what you could do is buy identical tennis balls and record how high they bounce when dropped from a roof of something you would want to do tests where the temperature is at least 5-10 degrees different and drop test like 10 times with at least 5 different temperatures you want to drop it because the force in bouncing it will be different also, make sure that the ground has the same texture (if you tested dry, make sure it’s dry in the other tests) you probably want to have someone help you record the height before you bounce you might want to let the balls sit for some time so it will have the same temp as the air
