Apparatus capable of recoding free falling body flat throw and inclined throw movements

Abstract

The invention belongs to the field of experimental device and relates in particular to a device which can record horizontal projectile motion and oblique projectile motion of a free falling body. The invention consists of a crude metal tube (1), an inner baffle (2), an outer baffle (3), a switch (4), an electronic positive booster (5), a battery case (6) and a neutral electrode (7). The invention has the advantages of simple structure, convenient operation, low cost and good practicality. The invention is very practical and applicable for teaching experiments in schools of depressed areas.

Description

technical field [0001] The invention belongs to the field of experimental devices, and in particular relates to a device capable of recording the motion of a free-falling body in flat throwing and oblique throwing. Background technique [0002] In physical kinematics, there is an experiment on how to do free fall, flat throw, oblique throw, etc. In order to know the motion state of a moving object within a certain period of time, it is necessary to record the trajectory of the object. Although there are many methods, but they are not ideal. At present, the methods used in kinematics include stroboscopic camera method, inkjet method, water sprinkling method and so on. The stroboscopic camera method is to use a video camera to aim at a moving experimental object for a fraction of a second of a gap video. The method uses a synchronous strobe light source to illuminate, or an adjustable rotating disk to make the camera lens open in a gap shape, and One is to make this moving o...

The stroboscopic camera method is to use a video camera to aim at a moving experimental object for a fraction of a second of a gap video. The method uses a synchronous strobe light source to illuminate, or an adjustable rotating disk to make the camera lens open in a gap shape, and One is to make the moving object flash regularly. Its shortcoming is that a video camera is necessary, and the price is more than several thousand yuan, which is relatively expensive.
