Question

explain the concept gravitational potential energy​

Answer 1

the energy possed by the body due to the planet's gravitational force. And it it different for different planet's

Answer 2

we know that energy can neither be created nor be destroyed, which means that energy remains conserve for an isolated system..

Thus for example ,when we lift abrick then how potential energy is get stored in it.

p.e. stored in the brick is actually come from the work we had done to lift it

So we can say that energy consumed in work done against gravity is the potential energy.

Hope it will help you.
