Velocity of Trolley Motion

The equipment is used for "Trolley Motion" experiment for primary school science. It is used for "comparing the speed of the object movement" experiment in junior middle school physics, to explore the relationship between the speed of the movement of trolley and the factors such as tension, friction surface, trolley mass, the number of small wheels of trolley.

Requirement:

1. The length of the track is not less than 800mm, which is convenient for experimental operation.

2. It is free to increase the weights and change the mass and pulling force of the trolley.

3. A light barrier is installed on the multi-functional trolley to measure the movement time of the trolley.

4. The number of small wheels can be changed without changing the mass of trolley. The experimental device consists of a multi-functional trolley, two kinds of frictional surface motion tracks, weights, and a ruler card slot.
