The Nature of Force
... Newton discovered the three basic laws of motion in the late 1600’s. Newton’s first law of motion states that an object at rest will remain at rest, and an object that is moving at constant velocity will continue moving at constant velocity unless acted upon by an unbalanced force. Newton’s fi ...
