Complete the sentence with an appropriate option. 

For a body falling freely from a height under gravity, its potential energy will be at its peak at __________. 

Potential energy is described as the energy stored as a result of a change in position relative to others, internal tensions, or a variety of other reasons.

Potential energy can be defined as the energy that an object possesses due to its position in a gravitational or electromagnetic field, or due to its internal state.

The available energy (u) = mgh  [where m = mass of the body, g =  gravity-induced acceleration,  h = distance from the ground].

When a body's height from the ground increases, so does its energy, and vice versa.

According to the reasoning above, the particle's kinetic energy is zero and its potential energy is maximal at the highest point. 

At the lowest point, potential energy is zero and kinetic energy is maximal as the ball approaches the earth.
