Question

A boulder that is resting on the top of a cliff slips over the edge and accelerates towards the ground. As the rock falls, the amount of kinetic energy
Responses
A increases.increases.
B decreases.decreases.
C stays the same.stays the same.
D increases then decreases.

Answer 1

As the boulder falls, it is accelerating due to gravity, which causes its speed to increase. Kinetic energy (\(KE\)) is given by the formula \(KE = \frac{1}{2}mv^2\), where \(m\) is the mass and \(v\) is the velocity of the object. As the boulder falls, its velocity increases, which means its kinetic energy also increases.

Therefore, the correct answer is:

**A increases.**
