Question

Justify that an object at a greater height has larger energy.

Answer 1

1. Potential energy: It is the form of energy that is possessed by an object by virtue of its position or configuration.
2. For example, water stored in a dam has potential energy due to its position with respect to the ground.
3. Potential energy due to the position of the object is also called gravitational potential energy.
4. The gravitational potential energy of an object of mass m which is placed at a height h above the ground level can be given as-
   $P.E=mgh$
5. $SinceP.E\propto h$, it means an object at a greater height has larger energy.
