text: When the ball is dropped or falls to the ground, anyone can pick it up so long as they are travelling in the same direction as play was when the ball was dropped.

text: If after being deflected the ball comes to rest on the player or his equipment, the ball must be dropped or placed on the green closest to where it came to rest.
text: When all three balls are dropped from the same height, the rubber ball will bounce the highest because it has the greatest elasticity.
text: So what happens to potential energy when a ball is dropped?
text: Because gravity has the most time to do its job when the balls are dropped from 75 centimeters, these balls have the most kinetic energy by the time they hit the ground.
text: Initially, before the ball is dropped, the ball's potential energy, E is given by E = mgh, where m is the mass of the ball, g is the gravitational acceleration and h is the height of the ball.
text: When the ball is dropped, the potential energy is converted to kinetic energy, and at the point of impact, , i.e. when the ball is level with the ground, and h = 0, the kinetic energy is E, given by E = 0.5mv2, where v is the velocity of the ball.
