If an object is moving with constant non-zero velocity, the net force on the object must be zero. This is because, according to Newton's first law of motion, an object in motion will remain in motion with a constant velocity unless acted upon by an external force. Since the object is already moving at a constant velocity, there is no need for any additional force to maintain its motion. Therefore, the net force on the object must be zero.
