... Using Newton’s Second Law, Fnet = m a. Since weight is a force, F = W. Since the acceleration caused by the force is due to gravity, a = g Since mass never changes, m = m Therefore W = m g Since the ball is traveling at a constant velocity, there is no acceleration; a = 0. According to Newton’s Seco ...
