WebAug 15, 2024 · Newton’s second law states that the magnitude of the net external force on an object is F n e t = m a. Since the object experiences only the downward force of gravity, F n e t = w. We know that the acceleration of an object due to gravity is g, or a = g. Substituting these into Newton’s second law gives. WebNewton’s First Law and Friction. Newton’s first law of motion states the following: A body at rest tends to remain at rest. A body in motion tends to remain in motion at a constant velocity unless acted on by a net external force. (Recall that constant velocity means that the body moves in a straight line and at a constant speed.)
