Second Law Of Motion Appartus

To demonstrate the Second Law of Motion in simple and accurate way, two identical balls — one drilled, the other solid — are used. When the release lever is triggered, the internal spring accelerates one ball and releases the other, showing that two balls dropped from the same height hit the ground at the same time even though one is traveling forward when the balls are released. Support stand and clamp required, but not included. With instructions.
