Question

A body in one dimensional motion has zero speed at an instant. At that instant, it must have (A) Zero velocity (B) Zero acceleration (C) Non-zero velocity (D) Non-zero acceleration

Tardigrade Admin · Accepted Answer

Magnitude of velocity = Speed So, if the speed is zero then it must have zero velocity also.

Q. A body in one dimensional motion has zero speed at an instant. At that instant, it must have

Zero velocity

Zero acceleration

Non-zero velocity

Non-zero acceleration

Magnitude of velocity $=$ Speed So, if the speed is zero then it must have zero velocity also.
