Principle

The mass of an object can be determined in different ways: by weighing the gravitational mass or by measuring the acceleration in the case of a known and constant accelerating force, which yields the inertial mass. This is based on the assumption that the gravitational mass and inertial mass are equivalent. In this experiment, a cart with different gravitational masses is accelerated on thedemonstration track. Its inertial mass is determined and the relationship between gravitational and inertial mass is derived.

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
