• 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 upright shaft.

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.
