Demonstration device for horizontal throw and collision experiments in physics

Abstract

The invention discloses demonstration device for horizontal throw and collision experiments in physics. The demonstration device comprises a bottom plate which is provided with a vertical plate. A fixed plate is arranged on the vertical plate. The fixed plate is connected with a support plate through a first connecting plate. A thread disc is rotatably connected on the fixed plate. A fixed block is connected on the lower side surface of the fixed plate. The fixed plate is connected with a rail through a second connecting plate. An empty slot is arranged in the fixed block. A push plate is connected on the slot bottom of the empty slot. A connecting strip is arranged on the push plate and connected with a vertical rod. One end of the vertical rod is engaged with the threads on the thread disc, and the other end is slidably connected in a limiting slot. A slide rod is fixedly connected on one end of the upper side surface of the bottom plate, and a second screw rod is rotatably connectedon the other end. The device can perform the simulation experiment of horizontal throw movement and object collision according to the experimental requirements and can obtain the parameters such as the movement time and the movement tracks so as to effectively improve the accuracy of the simulation experiment, reduce the experiment error, improve the success rate of the experiment and meet the physics experimental requirements.

Description

technical field [0001] The invention relates to the technical field of physical experiment supplies, in particular to a demonstration device for physics flat throw and collision experiments. Background technique [0002] Physics is a discipline that reveals the laws of nature and an important discipline that promotes technological progress. In order to improve the understanding of concepts in the teaching process and make it easier for students to understand the laws of physics, many experimental equipment will be used in the process of physics teaching. For example, the experimental equipment used to demonstrate the horizontal motion of objects combined with free fall, the experimental equipment to demonstrate the collision motion of objects, etc., the object is thrown horizontally at a certain initial velocity, if the object is only affected by gravity, such a movement is called Flat throwing motion, the flat throwing motion can be regarded as the combined motion of the u...

Problems solved by technology

For example, the experimental equipment used to demonstrate the flat throwing motion of the combination of horizontal movement and free fall of the object, the experimental equipment to demonstrate the collision motion of the object, etc. The object is thrown horizontally at a certain initial velocity. If the object is only affected by gravity, such a motion is called Flat throwing motion, flat throwing motion can be regarded as the combined motion of uniform linear motion in the horizontal direction and free fall motion in the vertical direction, flat throwing motion is a relatively important and classic physical model in physics, but the existing flat throwing motion 1. The demonstration device for the ball collision experiment has a single function and cannot adjust the initial parameters of the experiment, and the trajectory of the object is mostly viewed by the naked eye, which cannot intuitively reflect the trajectory of the object, and the timing is not accurate. To solve the problem The above problems The present invention provides a demonstration device for physics flat throwing and collision experiments
