Physical electrostatics teaching demonstration device

Abstract

The invention relates to a teaching demonstration device and particularly relates to a physical electrostatics teaching demonstration device, so as to solve the technical problem of providing a physical electrostatics teaching demonstration device which has an intuitive, vivid and simple demonstration process and enables students to understand the demonstration process. In order to solve the above technical problem, the invention provides the physical electrostatics teaching demonstration device, which comprises a bottom plate, a longitudinal guide rod, a rotating motor, a vertical plate, a box body, a bearing seat, a guide sleeve, a transverse motor, a longitudinal screw, a longitudinal nut, a transverse screw, a transverse nut, a transverse guide rod, a string, a small ball, a flat plate, a friction sheet, a thumb cylinder, an ejection plate and a longitudinal motor, wherein the bottom plate is provided with the longitudinal guide rod, the rotating motor, the vertical plate, the box body and the bearing seat sequentially from left to right; and a guide sleeve is arranged on the longitudinal guide rod. Effects that the demonstration process is intuitive, vivid, simple and straightforward and students can have deeper cognition and understanding on the experimental principle.

Description

technical field [0001] The invention relates to a teaching demonstration device, in particular to a physical electrostatic teaching demonstration device. Background technique [0002] Static electricity is a kind of electric charge in a static state. In dry and windy autumn, people often encounter this phenomenon in daily life: for example, when undressing at night to sleep, the crackling sound is often heard in the dark, accompanied by There is blue light; when meeting and shaking hands, as soon as the fingers touch each other, you will suddenly feel the pain of the fingertips, which is shocking; . [0003] Teaching demonstration means that teachers use certain props to show some specific examples in life to students through simple and clear demonstration methods, so as to simplify and visualize some abstract knowledge and principles, and help students deepen their knowledge and understanding of knowledge and principles . [0004] The demonstration process of the teachin...
