We’ve devised this apparatus to be an inclined plane, to examine collisions in one and two dimensions or to show conservation of momentum. Do any or all with one set-up. Consists of two 92cm long tracks of aluminum channel with 25mm sides. One track is closed at both ends and comes with two feet; the other is open at one end with a foot at the other. The first track features a spring-powered plunger for propelling a steel ball.
