Abstract
The utility model discloses a demonstrator of reactive movement of force. The demonstrator comprises a base plate, a guide rail, a slide block, a pillar, and a balloon. The guide rail is disposed on the center of the rectangular base plate and the guide rail and the base plate are integrated into one body. The slide block capable of sliding along the guide rail is disposed on the guide rail. The pillar is disposed on the slide block. The balloon is provided with an air nozzle equipped with a switch and is fixed on the pillar through the air nozzle. Air injected by the air nozzle of the balloon generates reactive force to drive the slide block to move along the guide rail toward the opposite direction in an accelerated manner. The demonstrator increasing the visual degree of an experiment has visualized and vivid demonstration and is convenient to the understanding of the characteristics of reactive movement. The demonstrator has characteristics of simple structure, easy manipulation, and repeated use.
Description
Technical field
The utility model relates to a kind of physical experiment apparatus, relates in particular to a kind of experimental demonstration device of recoil of the power of demonstration.
Background technology
At present, the middle school physics teaching material is when the experiment of demonstration recoil, usually the method that adopts is: add medicinal powder in thin glass tube, heat to thin glass tube with spirit lamp, when the medicinal powder in the thin glass tube is lighted, thin mouthful from rear end ejection rapidly of the combustion fire that generates, tubule just flies in the opposite direction.There is following drawback in experiment: the one, and the time ratio of thin glass tube motion is shorter, and because the effect of gravity, the track of thin glass tube motion is curve, and demonstration that can not visual pattern is not easy to the characteristics of correct understanding recoil; The 2nd, the experimental implementation more complicated is not easy to repeat demonstration.
Summary of the invention
The purpose of this utility model provides a kind of demonstrating visual image, the recoil demonstration device of power simple to operate.
The purpose of this utility model is achieved through the following technical solutions, the recoil demonstration device of this power comprises base plate, guide rail, slide block, pillar, balloon, described rectangular base plate middle part is provided with the guide rail that is connected as a single entity with base plate, described guide rail is provided with can be along the slide block of guide rail slip, described slide block is provided with a pillar, described balloon is provided with the air nozzle of a belt switch, and described balloon is fixed on the pillar by air nozzle.
Before the experiment, open the switch on the air nozzle, give balloon inflation, after balloon is full of gas, slide block is moved to the left end of guide rail, the experiment beginning, at first open the switch on the air nozzle, the gas in the balloon sprays from air nozzle, under the effect of recoil strength, slide block is accelerated motion round about, moves to right-hand member from the left end of guide rail.
The beneficial effects of the utility model: 1, demonstrating visual's image, with the jet generation recoil strength of balloon air nozzle, drive slide block along guide rail accelerated motion in the opposite direction, improved the visibility of experiment, be convenient to understand the characteristics of recoil; 2, simple in structure, easy to operate, reusable.
