High school physics horizontal projectile motion demonstration device

Abstract

The invention discloses a high school physics horizontal projectile motion demonstration device. The device comprises a first bracket, a base, a second bracket, a magnetic panel display screen, a working board, a magnetic ball, a shell, a groove, tension sensors and a display; the second bracket is arranged at the upper end of the base; the magnetic panel display screen is mounted to one side of the second bracket and is located above the base; the upper end of a telescopic rod is provided with the working board; the tension sensors are installed inside a protruding groove; the magnetic ball is disposed inside the groove; and the display is embedded into the front surface of the shell. The high school physics horizontal projectile motion demonstration device of the invention has the advantages of scientific and reasonable structure and safe and convenient use. According to the demonstration device, the telescopic rod is adopted, so that the working board can be fixed; a sandpit is adopted, so that damage to the base caused by the falling of the magnetic ball can be prevented, and therefore, damage to the appliance can be avoided; and a plumb line is set, so that whether the workingboard is level can be ensured, the accuracy and stability of the results of an experiment can be ensured; and the tension sensors are adopted, so that the results of the experiment can be more accurate.

Description

technical field [0001] The invention relates to the technical field of high school physics flat throwing motion demonstration device, in particular to a high school physics flat throwing motion demonstration device. Background technique [0002] Senior physics experts pointed out that high school physics is one of the foundations of high school science. It is a subject that studies the most general laws of motion and the basic structure of matter. Objects are thrown horizontally at a certain initial speed. If the object is only affected by gravity, such a motion is called Flat throwing movement, the simple and easy-to-understand demonstration device can help us understand the concept of flat throwing movement more intuitively. [0003] However, the high school physics flat throwing demonstration device currently on the market is not only complex in structure, but also has a single function. There is no telescopic rod, no working board, no sand pit, no ability to prevent the ...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a demonstration device for high school physics flat throwing movement, which can effectively solve the above-mentioned background technology that there is no telescopic rod, no working board can be fixed, no sand pit is set, the magnetic ball cannot be dropped to prevent damage to the base, and no lead is installed. The vertical line cannot ensure whether the working board is level, and the tension sensor is not installed, which cannot make the experimental results more accurate.
