What can be said about a body which is moving with a constant velocity?

(a) It is in static equilibrium

(b) It is in dynamic equilibrium

(c) It is in the state of non-equilibrium

(d) Its distance is conserved

I had been asked this question during an interview for a job.

This key question is from Laws of Motion topic in chapter Laws of Motion of Physics – Class 11

Best answer
The correct option is (b) It is in dynamic equilibrium

The explanation is: When a body is moving with constant velocity, there is no net force or moment acting on it. Hence, the body is in equilibrium. But since the body is moving, the equilibrium is known as dynamic equilibrium. Static equilibrium occurs when the body is at rest.
