Question

an object experiences a net zero external unbalanced force. Is it possible for the object to be travelling with 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

According to Newton's third law of Motion, No external force is needed to move an object with constant velocity. So, an Object travels with a constant velocity (non-Zero) When it experiences a net Zero external Unbalanced force. The magnitude of this velocity is constant and the direction is same as in the beginning.
An object may also not move at all if it experiences a net Zero external Unbalanced force. This is because, the object may be at rest in the beginning.

Answer 2

When an object experiences a net zero external unbalanced force, the acceleration is zero.

Thus, the either the object will be at rest or will move with a uniform velocity along a straight line.

0nce an object comes into motion and there is a condition in which its motion is unopposed by any external force.
