Question

When a body moves with a constant velocity, which of the following is/are correct about the motion?

• A. Average velocity and average speed is not equal.
• B. Average velocity is equal to zero but average speed is non-zero.
• C. Magnitude of displacement is equal to that of distance.
• D. Net force acting on the body is non-zero.

Answer 1

The correct option is C

Magnitude of displacement is equal to that of distance.

Since velocity is constant, hence net force acting on the body must be zero and direction and magnitude of velocity doesn't change which is equal to speed.
