Principle
An impulse acting on an object is defined as the change in
momentum caused by a force Fover a short period of time t. The
momentum p is defined as the product of force and time. It is
conserved, provided that there is no friction and that the
collision is elastic. This means that, although the objects in a
closed system with several objects can transfer or receive momenta,
the total momentum of the system remains constant over time and in
terms of its value, which in turn means that the energy is
conserved.
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
