A CART FOR DEMONSTRATING THE TRANSITION OF POTENTIAL ENERGY INTO KINETIC ENERGY · 模型 45627
The transition of potential energy into kinetic energy can be easily demonstrated using the cart described below. The trolley can be made of wheelsets of a simple design. To make a trolley, you need to take a plank about 1 cm thick (or thick plywood). At both ends of the wheelsets, drive in carnations without caps. Bearings are made of double sheet metal. When making a trolley, it is necessary to ensure that the axes of both wheelsets are parallel. Two holes are made on the trolley platform, into which two vertical racks with a cross section of 1x1 cm and a height of about 40 cm are tightly inserted, connected at the top with a bar of the same cross section as the racks. Not far from the top, a spool of thread is placed between the racks, strengthening it in the bearings in the same way as the wheels of a trolley. A thread is tied to the axle of the trolley, the other end of which is thrown over a coil with a load tied to it. Most of the trolley parts can also be made by 3D printing. When performing an experiment, the cart is moved by hand across the table. The thread is wound onto the axle, and the load is lifted, while storing potential energy. After that, the load is allowed to descend. At the same time, the cart starts moving.
