The unit is performed as a basement on height adjustable supports. A vertical rod is fixed on the basement. A bracket with an inclined plain fixed by means of joints is mounted in the upper part of the rod. Replaceable plates are mounted on the inclined plain. A ball fixed on a flexible suspension is moving on the plates. A photosensor registering the number of oscillations is also installed on the inclined plain.
An electronic stopwatch is used to fix the time of the pendulum oscillations.
The training system is supplied with technical and methodical documentation for teaching staff.
