Law of inertia (Newton's first law) with the demonstration track and the timer 4-4

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
