no, theoreticly speaking, it should be slower. the more weight, possibly the slower, the water would have little aero-dinamic quailities..
Yes. The force applied by the catapult will cause an acceleration on the tennis ball that is inversely proportional to the mass of the tennis ball.
because the tennis has more bounce in it your welcome
it would hit the ground if there was one to hit
If thrown at the same speed, a basketball. A basketball is heavier and will have momentum going with it while a tennis ball will have little momentum. A basketball will roll faster than most balls.
Wet, because in has more weight on it. If a tennis ball is wet it can't bounce it just falls and stays on the ground.
the hotter the tennis ball is the higher it will bounce because the molecules are moving faster and the pressure is decreasing. Opposite when it is cold.
because your arm is the one that's throwing the ball you are the on who controlls your are and that's why your arm is a catapult when you throw the ball
The transfer of energy from your racket and the ground to the ball causes its particles to move faster, which causes heat.
There is no evidence of a ball been made from polyurethane. There are polyurethane foam balls, but unfortunately no tennis balls. The process is likely to be the same as a normal tennis ball, the only difference being that the rubber in the ball is replaced by polyurethane.
In vacuum (no air) they both fall the same rate. In air, the golf ball falls faster because air resistance slows down the very light ping pong ball
a tennis ball
