Question

What kind of energy is possessed by the following?

Water is stored in the reservoir of a dam.

Answer 1

1. The energy possessed by its position or configuration is called potential energy.
2. It can be expressed as:

$\text{PE=mgh}$

Here, m is the mass of the object, g is the acceleration due to gravity and he is the height of an object above the earth’s surface.

Hence, the energy possessed by water stored in the reservoir of a dam is potential energy.
