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
