Question

a big stone on the top of a mountain has 150 j of gravitational potential energy. if it falls, what is the maximum amount of kinetic energy it can gain?
10 j
150 j
200 j

Explanation:

Step1: Apply energy - conservation principle

According to the law of conservation of mechanical energy, in the absence of non - conservative forces (such as air resistance being negligible), the maximum amount of kinetic energy gained by the falling object is equal to its initial gravitational potential energy.

Step2: Identify given values

The initial gravitational potential energy of the stone is given as 150 J.

Answer:

150 J
