Newton's 2nd law/ demonstration track

Principle

The distance-time law, the velocity time law, and the relationship between mass, acceleration and force are determined with the aid of the demonstration track rail for uniformly accelerated motion in a straight line.

Tasks

Determination of:

1. Distance travelled as a function of time
2. Velocity as a function of time
3. Acceleration as a function of the accelerated mass
4. Acceleration as a function of force.

Benefits

• Accurate results due to measurements with low friction: cart with sapphire bearings
• Over the entire track length adjustable feet for a very simple alignment of the track even on small tables
• Extremely robust accessories, for example no overloading of carts due to elastic bearing of base plate, prevent unnecessary breakdowns
• Detailed, illustrated step-by-step manual
• Timer 4-4 can be used for almost every experimental requirement: distance-time law for four distances, 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

Learning objectives

• Velocity
• Acceleration
