Walter Lewin’s horizontal motion experiment demonstrates a fundamental principle of classical mechanics: "the independence of horizontal and vertical motion" (inertia). In this experiment, a ball is launched vertically upward from a machine moving horizontally at constant velocity. Despite the machine’s motion, the ball falls back into it, illustrating that horizontal velocity does not affect vertical free fall. Unlike everyday intuition (where the machine might seem to "outrun" the ball) the ex
