If you drop it, tennis ball of course. Just because the basketball is bigger it doesn't have the same situated location point. However, if you put force in it it basketball.
less weight
It really depends how hard you bounce either one, but i think the tennis ball.
A tennis ball will bounce the highest because it is smaller. The smaller amount of mass that it has the more it will bounce and the higher it would get. For example, when you put air into a ball the more mass it builds up but, when the ball is flat it would not bounce.
I think a basket ball bounces the highest.
i know that a basketball will because if it has nothing in it, it won't bounce. right? but when you put more helium in, it will bounce high. but if you put to much in it, it might explode!!!!!!!!!!!!!!!!!!
a tennis ball
The major actions in the game resemble both the rules of tennis and the teamwork of basketball and soccer. The ball is similar to soccer, though using the hands as in basketball. The net is similar to badminton, or more widely to tennis, with which it shares beginning service from the rear line. It could be described as "handball soccer tennis badminton."
Basketball, baseball, soccer and football.
The Tennis ball is smaller and has less weight than a basketball. The tennis ball will also have less drag.
