Horizontal projectile motion demonstration device for high school physics

Abstract

The invention provides a horizontal projectile motion demonstration device for high school physics. The device comprises a rack, a lifting table, a background roller shutter assembly, a ball feeding assembly, a ball serving assembly and a sand table, and the lifting table is arranged on the rack in a lifting mode. The background roller shutter assembly and the ball feeding assembly are arranged onthe upper side of a top plate of the lifting table. The ball serving assembly is arranged on the lower side of a top plate of the lifting table. The ball serving assembly is connected to the lower end of the ball feeding assembly; a roller shutter of the background roller shutter assembly moves up and down between the machine frame and the lifting table, the sand table is arranged on the rack andlocated on the lower side of the roller shutter, a rail at one end of the ball serving assembly extends to one side of the roller shutter, and square paper is detachably arranged on the front side ofthe roller shutter. The horizontal projectile motion demonstration device provided by the invention solves the problems that an existing demonstration device is not visual in physical horizontal projectile motion demonstration process and a horizontal projectile motion path cannot be recorded.

Description

technical field [0001] The invention relates to the field of teaching aids, in particular to a demonstration device for high school physics flat throwing motion. Background technique [0002] At present, teachers usually explain knowledge points in an oral way when teaching, but physics knowledge is abstract to a certain extent, and it is difficult for students to grasp it with imagination. The flat throwing motion in high school physics is composed of horizontal uniform linear motion and free fall motion. The curved motion obtained by the synthesis of two linear motions, the high school physics flat throwing motion demonstration device is convenient for students to pass the flat throwing motion demonstration experiment. To understand the synthesis and decomposition of displacement, the existing demonstration device has the problem that the demonstration process of the physical flat throwing motion is not intuitive, and the path of the flat throwing motion cannot be recorded...
