Law of reciprocal actions (actio= reactio, Newton's thirdlaw) with the demonstration track and the timer 4-4  ![]()

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
