The Force & Motion Car demonstrates that the horizontal motion of an object is unaffected by forces which act solely in the vertical direction. The car's low-friction wheel bearings allow it to coast at an essentially constant speed. If the spring in the shaft is triggered while the car is coasting, the ball rises and falls right back into the shaft.
