Projectile motion experiment presentation device

Abstract

The invention discloses a projectile motion experiment presentation device. A recording groove is formed in the bottom of a support frame body. A sliding component is slidably installed at the top, and a horizontal projectile assembly is arranged on the sliding component for automatically releasing an experiment ball when the sliding component slides at uniform speed; one end of the support framebody is provided with a supporting component slidably installed in the height direction of the support frame body, an oblique projectile cylinder is arranged on the supporting component, the end, close to the recording groove, of the oblique projectile cylinder is open, the other end of the oblique projectile cylinder is hinged to the supporting component, an operation component is slidably installed inside the oblique projectile cylinder, and an elastic element is arranged between the bottom of the oblique projectile cylinder and the operation component. The device has the advantages that initial parameters of horizontal projectile and oblique projectile motion and related parameters generated when the motion is ended can be recorded, students can analyze and calculate the motion, and theexperiment presentation effect is good.

Description

technical field [0001] The invention belongs to the technical field of physical experiments, and in particular relates to a demonstration device for parabolic motion experiments. Background technique [0002] Parabolic motion refers to the motion of an object with a certain initial velocity only under the action of gravity within a small range near the ground. In high school physics learning, parabolic motion is a compulsory chapter, mainly including the study of flat throwing motion and oblique throwing motion. [0003] Flat throwing movement refers to the movement of an object under the action of gravity after it is thrown horizontally, and oblique throwing movement refers to the movement of an object under the action of gravity after it is thrown obliquely upward or downward. [0004] For the learning of these two kinds of parabolic movements, the most common demonstration method in the classroom is that the teacher demonstrates by means of parabolic movement. Therefore...

[0004] For the learning of these two kinds of parabolic movements, the most common demonstration method in the classroom is that the teacher demonstrates by means of parabolic movement. out of the direction, so students can't carry out follow-up analysis and calculation of the movement process through the teacher's demonstration, the demonstration effect is average, and it cannot meet the relevant requirements of the physical demonstration experiment
