Question

a stone of mass m is dropped from a height h. Prove that energy at any point in its path is mgh? ​

Answer 1

This is your answer bro...

Answer 2

The energy at any point in its path is mgh.

Explanation:

When a stone of mass m is dropped from a height h. The work is done by the stone. The work is due to the force of gravity such that work done is given by :

F = W = mg

m is the mass of object

g is acceleration due to gravity

Work done by an object is given by :

$W=F\times d$

$W=mg\times h$

When an object is dropped from a height, work done by it is mgh and as per work energy theorem, the work done is equal to change in kinetic energy.

Hence proved
