The velocity of two gliders, moving without friction on an air-cushion track, are measured before and after collision, for both elastic and inelastic collision.
1.A glider whose mass always remains unchanged collides with a second resting glider at a constant velocity. A measurement series, in which the velocities of the first glider before the collision and the velocities of both gliders after it are to be measured, is conducted by varying mass of the resting glider.
1.A glider, whose mass always remains unchanged, collides with a constant velocitiy with a second resting glider. A measurement series with different masses of the resting glider is performed: the velocities of the first glider before the collision and those of both gliders, which have equal velocities, after it are to be measured.
