Question

show that the potential energy of a body is completely converted into kinetic energy during its free fall under gravity​

Answer 1

Explanation:

Under free fall when a body falls due to the expression of gravity is height decreases so the potential energy also under the influence of acceleration due to gravity the velocity increases hence the kinetic energy this change occurs simultaneously and as we know that the mechanical energy of a substance is always remains constant so it is cleared then potential energy is converted into kinetic energy during free fall and at the end height become 0 so potential energy is zero and the velocity is maximum at the last moment so the kinetic energy is the maximum hence the all potential energy which was in the body has completely changed into kinetic energy.

Answer 2

Answer:

The correct answer of this question is a body accelerates due to gravity, its velocity increases, resulting in kinetic energy.

Explanation:

Given - The potential energy of a body is completely converted into kinetic energy during its free fall under gravity​ .

To Find - Show that the potential energy of a body is completely converted into kinetic energy .

When a body falls due to gravity, its height decreases, resulting in potential energy. When a body accelerates due to gravity, its velocity increases, resulting in kinetic energy. This change occurs simultaneously, and because we know that a substance's mechanical energy is constant, it is cleared. Potential energy is converted into kinetic energy during free fall, and at the end of the fall, the height becomes zero, resulting in potential energy.
