Question

Water stored in a dam primarily possesses

• A. Heat energy
• B. Electrical energy
• C. Kinetic energy
• D. Potential energy

Answer 1

The correct option is D Potential energy

Answer is D.

Potential energy is the energy that is stored in an object due to its position relative to some zero position. An object possesses gravitational potential energy if it is positioned at a height above (or below) the zero height.
There is potential energy stored in a water reservoir behind a dam. It is converted to kinetic energy when the water starts flowing down the penstock, from the dam. This kinetic energy is used to turn a turbine.
Hence, the water stored in a dam possesses potential energy.
