Principle

If, following an acceleration, an object is not subject to any
external force, the object will remain in the state of a uniform
motion. The aim of this experiment is to use the demonstration
track and to measure the velocity of a uniformly accelerated cart
in order to demonstrate that the velocity of the cart remains
constant after the completion of the acceleration process.

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
