Four Demonstration Experiments for the Price of Only One
- We include seven 19mm steel balls and complete instructions
- Stand not included
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.
