It depends. A shot with backspin will drop a lot faster then a topspin or flat shot.
A new tennis ball will bounce higher. Old tennis balls are considered "dead."
I am assuming you are talking about tennis. On a grass surface, the ball will bounce fast. On clay courts, the ball will bounce slower than on grass. On a hard court, the speed of the ball bounce will be in between clay and grass.
there is air inside a tennis ball. when it is hot, the air inside the ball is hot, and thus is excited. when the gas is excited it bounces around more inside the ball and causes it to be harder. when it is colder the gas is less excited so the ball feels softer. When you bounce a tennis ball on a hot day the ball is harder feeling and is essentially more elastic. this causes the ball to bounce higher. when it is colder the ball is less elastic and will not bounce up very high at all. think about the moment the ball hits the ground. if you threw it super hard the ball would momentarily get dented in. now if its hot the gas is excited and moving around a lot so it will push the dented in ball back out to its original shape very fast, where as if it is cold it will not push it back out as fast or hard so it will not bounce as high.
depends on what height you drop it like 5 inches its 2 seconds
You have to hit it after the bounce. Normally if its a medium speed wait until its level with your body and hit through at that point. If its very fast put your racket just in front of you and parry the ball back into the court.
120 mph
It's 100% the tennis ! In tennis you always keep active while you concentrate on the ball and the ball is pretty fast you can't stop moving until you win the round or loose the round.For example in football you can stop running if the ball isn't with you and even there is subtitution...So tennis is more active than swimming because swimming you relax in water which you are fast,while tennis you keep running right side and left side so the most active sports is tennis...

An example might be - Tennis is a fast-paced sport. Another example is - The tennis ball shattered the window.
It depends. If a tennis balls are hit with the same amount of force, then the dry tennis ball will travel faster and farther. However, if the two tennis balls begin traveling at the same speed, then the dry tennis ball will slow down more rapidly than the wet tennis ball. The reason is the added mass of water. It would take more force to make the wet tennis ball fly as fast as the dry, but the added mass also requires more force to slow down the wet ball.
It will go as fast as it's terminal velocity
You need to know the area of the glass, its span, how it is supported, and how thick it is; also you need to know the stiffness of the tennis ball; so this is a complex problem.
i think it is how fast u react to fast sport movements like: (hitting a tennis ball with a tennis racquet as quick as u can) i am not sure but i think hat is what it means
