Does all object in motion have forces acting on them?

Not all the object in motion have net force acting on them. Only accelerating or bodies changing their velocities are under net force. Therefore, motion of a body in a straight line with constant speed doesn't require any force to continue it. But, if body requires to speed up or speed down, the net force should be applied on it. read more

All objects in motion have net forces acting on them An object is moving to the right in a straight line. The net force acting on the subject is also directed to the right, but the magnitude of the force is decreasing with time. read more
