Fundamental law of dynamics (Newton's second law) with the demonstration track and the timer 4-4

Principle

If an object is subject to constant force, it undergoes constant acceleration. Its change in motion is proportional to the accelerating force. The aim of this experiment is to describe the relationships between the acceleration of a cart and its mass or the accelerating force with the aid of 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
