Question

Prove that mechanical energy remains constant for a free fall

Answer 1

Answer:

Prove that mechanical energy remains constant for a free fall

Explanation:

It may be shown that in the absence of external frictional force the total mechanical energy of a body remains constant. Let a body of mass m falls from a point A, which is at a height h from the ground as shown in fig. ... Under the force of gravity, the mechanical energy of a body remains constant.

Answer 2

Explanation:

☑️It may be shown that in the absence of external frictional force the total mechanical energy of a body remains constant. Let a body of mass m falls from a point A, which is at a height h from the ground as shown in fig.

Under the force of gravity, the mechanical energy of a body remains constant.
