Conservation of momentum in multiple inelastic collisions with the demonstration track and the timer 4-4

Principle

During inelastic collisions, kinetic energy is withdrawn from the system and converted into internal energy, which is no longer available for motion. As a result, the kinetic energy decreases with every collision. During this process, the objects usually undergo deformation before they continue to move in a joint manner with a momentum that corresponds to the sum of the individual momenta before the collisions.

Benefits

• Accurate results due to measurements with low friciton: cart with sapphire bearings
• Over the entire track length adjustable feet for a very simple alignment of the track even on small tables
• Extrem robust accessories, for example no overloading of cars due to elastic bearing of base plate, prevent unnecessary breakdowns
• Timer 4-4 can be used for almost every experimental requirement : distance-time law for four tracks, measurement of speed at four positions, principles of collisions, measurement of the orbiting time of a rotary movement, the direct measurement of the duration of a complete swing of a mechanical pendulum and for short or long-term measurements with two 8-digit displays by connecting each of 2 timers
