Question

An object experiences a net zero external unbalanced force. Is it possible for the object to be a non-zero velocity? If yes, state the conditions that must be placed on the magnitude and direction of the velocity. If no, provide a reason.

Answer 1

The net force is zero, the acceleration is zero, and the velocity of the object remains net force acting on an object is zero, either the object will be at rest or it will move with a constant (uniform) velocity.

Thus, a moving object will continue to move with the same velocity after the external unbalanced force becomes zero.
