Principle
An impulse acting on an object is defined as the change in
momentum caused by a force F over a short period of time
t. The momentum p is defined as the product of
force and time. It is conserved, even over several collisions,
provided that there is no friction and that the collision is
elastic.
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
