>> 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
