Embodiment 1

[0025] Embodiment 1: use polyvinyl chloride (PVC) material to make the tabletop (21), tripod (22), motor frame (24), turntable (29), battery tank two (27) and gyro launcher of electrostatic levitation table Shell (16), bull gear (17), pinion (18), top (13), push rod (14), battery slot one (19). Make a brush (23) out of sheep fur. High-speed motor (11) can adopt Yunhui board 130 model miniature high-speed motors. High-torque motor (25) can adopt the R280 model miniature high-power motor of Zhongao Motor brand. Switch one (12) and switch two (26) can choose the Risym brand PBS-33B model push type switch for use.

[0026] Method 1: Install the gyro on the gyro transmitter, start switch 1 (12) to keep the gyro (13) rotating at a high speed, and at the same time make the gyro close to the electric brush (23), so that the gyro (13) and the electric brush (23) ) produces effective friction to electrify the top (13) ( Figure 4 ). Move the gyro transmitter together with the gyro ...

Abstract

The invention relates to an electrostatic suspended gyroscope for physics experiment classroom demonstration, and belongs to the field of physics experiment instrument design in the middle school class. The electrostatic suspended gyroscope is composed of gyro emitter and electrostatic suspension table. The problems of single experiment effect, low experiment rate and difficulty in arousing students' learning interest in present electrostatic phenomenon teaching can be solved. The electrostatic suspended gyroscope is characterized in that the gyro made of the lightweight insulating material issuspended over the suspension table with the same electrostatic charge by means of the electrostatic force through frictional electrification. The repulsive action of the same charge, the phenomenonof frictional electrification and the effect of moment of inertia on the stability of the object can be successfully demonstrated, and the relationship between the electrostatic force and the distancebetween the charges can also be qualitatively explained. The electrostatic suspended gyroscope has the advantages of simple structure, easy operation, high interestingness in the experimental phenomena, sufficient attraction for classroom demonstration and arousing students' strong desire for knowledge and curiosity.

Description

technical field [0001] The invention belongs to the design field of middle school physics classroom experiment instruments, in particular to a physics teaching device used in physics classrooms to demonstrate electrostatic interaction experiments. Background technique [0002] The phenomenon of static electricity was discovered as early as in ancient Greece. Thales of the Miletus Academy found that amber rubbed with fur could attract light and small objects, but he thought it was because amber was magnetized, and he thought it was a kind of magnetism. Phenomenon. It was Gilbert during the scientific revolution that really brought electricity into the field of scientific research. In his "On Magnetism" in 1600, he proposed that the attraction of amber to small objects is an electrical phenomenon, which is different from magnetic phenomena, and imitated the Greek word amber (elektron). ) coined the Latin word for "electricity" (electricus). It is obviously inefficient to dir...
