This instrument is used to demonstrate the interactive transformation of kinetic energy and potential energy and the conservation of mechanical energy.
The product is mainly composed of wheels, rolling shaft, base, stand, beam, etc. The two ends of the rolling shaft have small holes for threading.
The small holes at both ends of the rolling shaft are threaded and fixed firmly, and hung on the bracket to make it level. Then, twist the roll shaft by hand to raise the roll, and the suspension wire is wound on both ends of the shaft at the same time. When the rolling pendulum rises to the near point, let go, the rolling pendulum will spin down under the action of gravity, and it will turn faster and faster.
When the roll drops to its lowest point, that is, when it no longer drops, it continues to rotate due to inertia, and it starts to rise again around the suspension line. When it rises to the same height as the previous time (slightly lower than the previous height), it stops rising, and then falls under the action of gravity. This rises and falls repeatedly, and finally stops completely.
Note: After use, coat the roller pendulum with anti-rust oil.
