Problems solved by technology

[0007] The existing flat-throw motion demonstrator is too simple to show the motion facts more objectively during the demonstration, and the position and initial speed of the ball remain unchanged, which makes the experimental demonstration effect incomplete and affects the quality of teaching
[0008] Moreover, the flat-throwing motion demonstrator on the market is only used as a flat-throwing de

Abstract

The invention particularly relates to a physical teaching aid capable of achieving crossed teaching demonstration and a teaching method. The physical teaching aid organically combines horizontal projectile motion, force balance, and circuits in physics. A rotating motor drives a wire winding rod to rotate. The wire winding rod tightens or loosens a pull rope in order to drive a first track to rotate around a second track. The falling gradient of balls is changed in order to change the initial speed of the horizontal projectile motion and a horizontal projectile trajectory. A demonstration board enhances the display of the horizontal projectile trajectory of the balls. A baffle blocks the balls and the balls fall on a rollback slideway and roll to the left end of the rollback slideway so asto further drive a balance demonstration component to operate. The balls continuously enter the right leg of a piston cylinder to move downward the piston plate of the right leg. Due to force balance, the liquid in the piston cylinder moves and the piston plate of the right leg moves upward so as to realize the visual display of the force balance. The piston plate of the right leg gradually movesup under the influence of the force balance, a lower metal block contacts an upper metal block, and a contact switch is closed so that an indicator light is turned on to achieve the visual display ofthe circuit.

Description

technical field [0001] The invention relates to the technical field of physics teaching aids, in particular to a physics teaching aid capable of cross-teaching demonstration and a teaching method. Background technique [0002] Physics is a subject that studies the most general laws of motion of matter and the basic structure of matter. As the leading discipline of natural science, physics studies the most basic forms and laws of motion of all matter, ranging from the universe to elementary particles, and thus becomes the research basis of other natural science disciplines. Its theoretical structure fully uses mathematics as its working language, and experiments are the sole criterion for testing the correctness of the theory. It is the most sophisticated natural science discipline today. [0003] Physics is mainly divided into several major sub-neighborhoods such as mechanics, heat, optics, and electromagnetism. [0004] Among them, in mechanics, flat throwing motion is a ...
