Both balls can bounce on grass. don't believe me. try it on your own
It really depends how hard you bounce either one, but i think the tennis ball.
No,of course not, the friction between the basketball and the grass would make the ball bounce less.
The Tennis ball is smaller and has less weight than a basketball. The tennis ball will also have less drag.
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!!!!!!!!!!!!!!!!!!
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.
less weight
Because it has a soft surface.
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.
A tennis ball because it is smaller so it contains less air, causing it to bounce higher.
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.
Grass of course! Grass is more solid than dirt.
A basketball will bounce more on concrete because it is a flatter surface then carpet and grass
