Small ball motion simulating device

Abstract

The invention discloses a small ball motion simulating device, which comprises a bracket, wherein the bracket comprises a lower bottom plate, a left supporting arm and a right supporting arm, and a horizontal projectile motion structure, a free falling body motion structure and a vertical throw-up motion structure are arranged on the bracket; the horizontal projectile motion structure comprises afirst photoelectric gate and a sliding rail; the free falling body motion structure comprises an electromagnet and a convex brim; the electromagnet is fixedly mounted on the lower side surface of theconvex brim; the vertical throw-up motion structure comprises a ball receiving plate and a U-shaped rail which is arranged under the ball receiving plate and connects the upper and lower ends of the ball receiving plate; the rear side surface of the two supporting arms is provided with a magnetic drawing board provided with magnetic powder, and the small ball is an iron ball or a magnetic iron ball; and a flattening structure is arranged at the lower part of the bracket. The invention aims to solve the technical problem of providing the small ball motion simulating device, the small ball motion simulating device can simulate vertical motion situation of the small ball vividly, and the small ball motion simulating device is provided with the magnetic drawing board capable of displaying a motion trajectory, so that a teacher can mark and explain directly on the drawing board.

Description

Technical field [0001] The invention relates to an experimental instrument for small ball movement, in particular to a small ball movement simulation device. Background technique [0002] At present, you will encounter more physics knowledge in the domestic high school learning stage, especially the analysis of object motion. The three most typical object motions are: 1), vertical throwing motion; 2), horizontal throwing motion; 3 ), free fall motion. However, most teachers use hand-drawn drawings or electronic animations to analyze and explain to students, but they cannot demonstrate and explain more realistically to students through certain devices, so that students can only remember knowledge through abstract imagination and rote memorization; Some teachers will roughly simulate the trajectory of the object by throwing animals to describe it vividly, but this is not a good way to use data analysis, and it cannot directly form a trajectory, let alone explain and analyze it dir...

Problems solved by technology

However, most teachers analyze and explain to students through hand-drawing or electronic animation, but they cannot give students more realistic demonstrations and explanations through some kind of device, so that students can only remember knowledge through abstract imagination and rote memorization; less Some teachers will roughly simulate the trajectory of the object by throwing objects to describe it vividly, but this cannot be used for data analysis very well, and it cannot directly form a trajectory, let alone explain and analyze it directly on the trajectory
