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