Abstract

The invention discloses a mechanical energy conservation tester which comprises an iron frame platform, a panel and a pendulum module, wherein the iron frame platform comprises a rod piece fixed on a base; the panel is fixed on the rod piece; the panel is a semicircular plate body and provided with an experimental data identifier in a circumferential direction of the semicircular plate body; the pendulum module comprises a pendulum head, a pendulum strip and a pendulum bob; the pendulum head is fixed at the circle center of the panel; the top end of the pendulum strip is connected with the pendulum head by a ball bearing and swings from side to side by using the ball bearing as a base point; and the bottom end of the pendulum strip is fixedly connected with the pendulum bob. The mechanical energy conservation tester disclosed by the invention has the advantages of simplicity, practicability, easiness for assembling, stable experiment, high accuracy and small error.

Description

technical field [0001] The invention relates to a mechanical energy conservation tester, which belongs to the field of educational equipment. Background technique [0002] The experimental principle of the mechanical energy conservation tester is: under the condition of only gravity doing work, when the kinetic energy and potential energy of an object are transformed into each other, the total amount of mechanical energy remains unchanged, that is, the sum of potential energy EP and kinetic energy EK is a constant. The conclusion is called the law of conservation of mechanical energy. [0003] The conservation of mechanical energy is verified by the pendulum (ball) method and the ramp method. The pendulum (ball) method is: a metal cylinder is made into a simple pendulum, which can be used to study the relationship between kinetic energy and potential energy at any time during the swing process. When the pendulum (ball) passes through the photogate, the instantaneous velocit...
