Problems solved by technology

The above-mentioned patents have the following deficiencies: first, the movement of the trolley on the inclined plank cannot well overcome the frictional force, and it is easy to cause the trolley to roll over; The paper tape is easy to get stuck in the dot timer, causing the experiment to fail. In addition, the dot timer equipment is prone to failure, causing the paper tape to be entangled
And above-mentioned patent can not solve this kind of problem, therefore, in order to solve the above-mentioned problem, the present invention proposes a kind of new acceleration experiment demonstrative device for physics teaching

Abstract

The invention discloses an acceleration experiment demonstration device for physics teaching. The acceleration experiment demonstration device comprises a substrate, support rods are welded on opposite sides of the outer wall of the top of the substrate, the outer walls of the top of the two support rods are welded with a guide rail, equidistantly distributed air outlet holes are arranged at bothsides of the outer wall of the top of the guide rail, a slide block is disposed on the guide rail, a longitudinal section shape of the slide block is an inverted triangle, and the outer wall of the top of the slide block is fixed with a light shielding plate by the bolts, a buffer cylinder is fixed on one side of the outer wall of the top of the guide rail by the bolts, the outer wall of one sideof the guide rail is provided with a scale, the guide rail has a circular through hole at one end, an intake pipe is inserted into the circular through hole, and the outer wall of the top of the substrate is provided with a T-shaped groove parallel to the guide rail. The acceleration experiment demonstration device not only breaks through the positive triangle shape of the existing air-cushion guide rail, but also prevents the side-turning of the slide block when sliding in the guide rail, and can fully buffer and stop the sliding block to prevent collision damage of the slide block due to toofast speed at the end of the movement.

Description

technical field [0001] The invention relates to the technical field of physics experiments, in particular to an acceleration experiment demonstration device for physics teaching. Background technique [0002] In physics learning, physical experiment is a very important link, and as a more important experiment in physical mechanics is physical acceleration experiment, there are mainly two kinds of experimental devices used in physical acceleration experiment in physical learning at this stage: air cushion There are often certain errors in the guide rail and the inclined plate trolley, which can only be realized under hypothetical conditions, which will directly affect the accuracy of the experiment and cannot be directly explained. The block is buffered, which is easy to cause the collision damage of the slider. Therefore, the existing technology cannot well meet the various necessary requirements in the physical experiment, and we need to innovate the existing technology. ...
