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 condition that must be placed on the magnitude and direction of the velocity if not provide a reason answer in short

Answer 1

Yes, even when the net external force is 0, an object may travel with constant velocity.

The only condition is that it should move with same constant velocity and it should be moving in the same direction.

For example: - A rain drop falls with constant velocity.

Answer 2

Yes, it is possible in uniform circular motion in which velocity has the direction as same as direction of tangent. Its magnitude remains uniform
