As a Boulder rolls from the tip of hill to the bottom how does its potential and kinetic energy change
A. potential and kinetic energy both increase
B. Potential increases and kinetic decreases
C. potential decreases and kinetic increases
D. potential and kinetic energy both decrease
The answer is C, because the ball has potential energy when sitting at the top of the hill, once it starts rolling from an increased height, the potential energy decreases as the kinetic energy increases.
