Question

Derive the expression for potential energy.Give any two examples for potential energy.

Answer 1

Answer:

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

∴E

p

=mgh
