Laws of collision/ demonstration track with a 4-4 Timer
P2130505
Elastic collision: calculated energies after the collision as functions of the mass ratio of the gliders.
Principle The volocities of two gliders, moving without friction on a demonstration track, are measured before and after collision, for both elastic and inelastic collision.

Tasks 1. Elastic collision 1. The impulses of the two gliders as well as their sum after the collision. For comparison the mean value of the impulses of the first glider is entered as a horizontal line in the graph. 2. Their energies, in a manner analogous to Task 1.1 2. Inelastic collision
