According to Newton's first law of motion, an object in motion will remain in motion at a constant velocity (which includes speed and direction) unless acted upon by an external force. If there are no other forces acting on it, the characteristic of the moving object that would remain constant is speed. Thus, if there are no forces, the speed of the object remains unchanged.
