Principle

A cart is repeatedly accelerated to a constant velocity by way of a mechanical starter system. The runtime of the cart is determined at various intervals. These values are then used to determine the average velocity.

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
