Question

Water stored in the dam possesses

• A. No energy.
• B. Kinetic energy.
• C. Potential energy.
• D. Electrical energy.

Answer 1

The correct option is C Potential energy.

Water stored in a dam remains at rest.
The kinetic energy of water will be zero , as its speed is zero.

Kinetic energy of water , $K=\frac{1}{2}m{v}^2=\frac{1}{2}m\times (0{)}^2=0$

The level of water in dam rises when more water is added to it, Thus, gravitational potential energy of water increases.

So, we can say that, the water stored in a dam possess potential energy.

Hence, option (c) is the correct answer.

Definition of Potential energy: Potential energy is a form of mechanical energy possessed by an object by virtue of its position relative to others. Definition of Kinetic energy: Kinetic energy is a form of mechanical energy possessed by an object by virtue of its motion relative to others.
