This is an old experiment. Neither. Both balls have the same velocity as gravity draws on them equally.
A bouncy ball.
Zero.
it's not as bouncy
Usually very bouncy, more bouncy then a tennis ball or basically any other sports ball
It has more pressure
The factors that affect the bounce of a dropped ball include...... the height from which it is dropped; the force applied to it, if any, when dropped; the acceleration of gravity, which is different depending upon what planet you're on ; the elasticity of the ball; the density of the atmosphere, which affects "air resistance"; and the rigidity and elasticity of the surface on which the ball bounces.
a tennis ball will bounce the highest as in sports or a bouncy ball bounces higher than that
It could if you slammed the bouncy ball on the ground hard enough, or if you dropped it from a 30 story building. probably not
31 m/s
A golf ball is cold and hard while a tennis ball is "warm and fuzzy" :O)
The initial velocity of a dropped ball is zero in the y (up-down) direction. After it is dropped gravity causes an acceleration, which causes the velocity to increase. F = ma, The acceleration due to gravity creates a force on the mass of the ball.
Under the fuzzy exterior of a tennis ball is a rubber "shell". Rubber has a natural bouncy quality, but it's the compressed air inside the rubber shell that gives it that extra bounce. If you ever heat up a screwdriver and push it through the tennis ball, you should hear the air hissing out, or whooshing out in some circumstances. Hope this helped, Chris
