because the rubber is newer and not worn at all...plus the older one might be made of leather...there could also be less air in the older one.
It really depends how hard you bounce either one, but i think the tennis ball.
it depends if the softball is heavier than the baketball then no it will bounce lower. If a basketball is heavier than a softball it will bounce higher because of gravity
Of course yes.
less weight
absolutely
yes
The Tennis ball is smaller and has less weight than a basketball. The tennis ball will also have less drag.
Yes. A full basketball with medium to high pressure will clearly bounce higher than a flat basketball with low pressure.
Soccer balls. It would depend how high they came down from. As soccer balls are kicked high into the air, they probably bounce higher than basketballs which are just thrown.
A golf ball would bounce higher than a basket ball.
it will bounce higher if there is more air. ex. Flat basketball- being flat, the ball will just hit the floor and will be pressed inwards on the spot it landed pumped basketball- being full of air, the ball hits the ground and like a flat basketball is pressed inwards. but because there's air in it, the air will make the ball retain its shape and bounce.
The basketball at room temperature has more energy, because cold is just the absence of energy. The ball that is frozen would not bounce as high because it is wanting to stay in that shape, and has less time to react.
