Problems solved by technology

Although this experiment can verify the law of conservation of momentum, in the actual teaching process, because it has no direct speed measurement function, but calculates the speed according to the law of flat throwing motion, there are too many comprehensive physical laws, which increases the burden for students to understand. It is not possible to demonstrate the bounce of a ball with a small mass when it collides with a ball with a large mass

Abstract

The invention provides a momentum conservation experimental instrument. The experiment instrument is mainly composed of a switch, a back plate, an electromagnet, colliders, a shading piece, sliding rails, a left side plate, a horizontal support, a tachymeter, adjusting bottom feet, a bottom plate, a photoelectric door, a gradienter, a right side plate and the like. The joints of the back plate, the left side plate, the bottom plate and the right side plate are vertically and fixedly connected to form an integral frame, the two sliding rails penetrate through the two colliders at the same timeand are horizontally fixed between the left side plate and the right side plate. The switch is fixed to the center of the upper portion of the back plate, the instantaneous speeds of the colliders canbe directly read out through the tachymeter, the experiment process is rigorous, the law of conservation of momentum can be quantitatively studied, the experiment is simple, easy to operate, convenient to use, visual and capable of being organically combined with traditional experiments, and development of experiment exploration teaching is better facilitated.

Description

technical field [0001] The invention relates to a physical experiment teaching instrument, in particular to a momentum conservation experimental instrument. Background technique [0002] The "Law of Conservation of Momentum" in textbooks 3-5 of "Physics" published by the People's Education Edition is one of the basic theories of physics in senior high school. The ball collides with a small ball that is stationary on a horizontal track, puts carbon paper on the white paper, and determines the flying distance by the impact marks left on the carbon paper and white paper after the ball hits the ground. Although this experiment can verify the law of conservation of momentum, in the actual teaching process, because it has no direct speed measurement function, but calculates the speed according to the law of flat throwing motion, there are too many comprehensive physical laws, which increases the burden for students to understand. It is not possible to demonstrate how a ball with ...
