Principle

If no external force acts on a closed system of objects, the total momentum p of the system is conserved and the centre of gravity of the system remains constant. If the only interaction between the objects is elastic collisions, the energy is also conserved. If one object exerts a force F on a second object, an opposite force -F acts on the first object. In this experiment, this will be demonstrated by way of two carts on the demonstration track.

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
