Which describes the difference between a bowling ball sitting in the rack waiting to be used and the bowling ball knocking pins down?

A.

In the rack, the bowling ball has no energy at all. As it knocks down the pins the energy is 75% kinetic and 25% potential.

B.

In the rack, the bowling ball has only kinetic energy. As it knocks pins down, its potential energy has increased, while its kinetic energy has decreased.

C.

In the rack, the bowling ball has only potential energy. As it knocks pins down, its potential energy has decreased, while its kinetic energy has increased.

D.

In the rack and when knocking down pins, the potential energy and the kinetic energy of the bowling ball are equal.

Bernard Winters · Answer 1

It is A ...

Breean · Answer 2

I would Say B. because as the ball is rolling the energy increase depends on how hard you roll the ball ... the speed is based on the energy it's self
