Question

Derive the expression for gravitational potential energy?

Answer 1

Considering mass $"m"$ and height $"h"$

We have formula,

$w=fh$ ........(1)

and

$f=mg$ ........(2)

From (1) and (2), we have,

$w=mgh$

Gravitational potential energy is given by,

$E_p=w$

$\therefore E_p=mgh$

Hence, this is the answer.
