Question

A body is at rest. It may possess

• A. energy
• B. momentum
• C. speed
• D. velocity

Answer 1

The correct option is A

energy

The correct option is A for the following reasons:

1. An object at rest may possess potential energy.
2. Potential energy is by virtue of position of the object at rest.

The explanation for the other options:

B. Momentum is the product of mass and velocity. So the object is in motion.

C. Speed is the distance covered by an object in a unit time. This represents the object is in motion.

D. Velocity is the rate of change of displacement. This again represents the object is in motion.

Thus the object at rest may possess energy.
