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
