Would a tennis ball bounce higher if dropped onto concrete or a trampoline?

Question

also, would the outcome change if the ball used was solid (metal or a pool ball) instead of a compressable one?

Answer 1

concrete

Answer 2

the tennis ball would bounce higher on concrete, this is because a tennis ball is hollow on the inside and uses a "trampoline" effect when impacting a hard surface to propel it back up.  When it hits the actual trampoline, the kinetic energy of the ball is absorbed and dispersed across the surface area of the trampoline.  The balls light mass keeps it from rebounding as it does not have as much force as a say pool ball.

Answer 3

Concrete.  The way the bounce works is that the ball is distorted by the force of hitting a solid surface -- it actually stores some of the energy of the impact and then pops back into shape.  If you drop a tennis ball onto a trampoline, both objects absorb some of the force, so it isn't as efficient.

Answer 4

concrete because the trampoline will absorb alot of the power the ball will need to bounce hight, where as on concrete there is a very stable place for the ball to propel itself off of that surface rather then its kinetic energy being wasted.

Answer 5

definitely concrete because the trampoline will just absorb all the energy so it has less enrgy pushing it back up.

Answer 6

i think concrete
