Galileo motion conjecture verification instrument

Abstract

The objective of the invention is to better verify Galileo motion conjecture. The invention provides a Galileo motion conjecture verification instrument. The instrument is mainly composed of timers, arc-shaped baffles, a photoelectric switch, a single-side movable plate, a small ball, an electromagnet, a movable supporting plate, a bottom plate, a panel, a relay, a power source and the like. The panel and the two arc-shaped baffle plates form a storage box at the left end of the bottom plate; the single-side movable plate is mounted between the two arc-shaped baffle plates through a rotating shaft; the single-side movable plate can rotate around the rotating shaft; a movable supporting plate is further arranged on the back surface of the single-side movable plate to assist in supporting the single-side movable plate; the first timer and the second timer are fixed on the panel; the electromagnet, the photoelectric switch and a relay design circuit are used for controlling the two smallballs to start moving at the same time, the two timers are automatically started, timing is conducted separately to display the exact time, the moving speeds of the two small balls with different masses are compared, and development of experiment exploration teaching is better facilitated.

Description

technical field [0001] The invention relates to a middle school physics teaching and experiment instrument, in particular to a Galileo motion conjecture verifier. Background technique [0002] In the sixth chapter of the second chapter of "Physics" Compulsory One of Senior High School "Galileo's research on free fall", it is a symbolic content of the new textbook that pays attention to process and method, emotional attitude and value. Therefore, through the study of this class, can students experience human beings' thinking and methods of exploring the natural world, and feel the nobleness of a great scientist? Sentiment becomes the ultimate goal of this lesson. In the actual teaching process, there is no suitable instrument to verify Galileo's motion conjecture. Most teachers play projection or video materials, and students need to understand Galileo's conjecture that objects with different masses move along an inclined plane. The speed of free fall follows the same law. B...

[0002] In the sixth chapter of the second chapter of "Physics" Compulsory One of Senior High School "Galileo's research on free fall", it is a symbolic content of the new textbook that pays attention to process and method, emotional attitude and value. Therefore, through the study of this class, can students experience human beings' thinking and methods of exploring the natural world, and feel the nobleness of a great scientist? Sentiment becomes the ultimate goal of this lesson. In the actual teaching process, there is no suitable instrument to verify Galileo's motion conjecture. Most teachers play projection or video materials, and students need to understand Galileo's conjecture that objects with different masses move along an inclined plane. The speed of free fall has the same law. Because there is no real experimental demonstration, some students will question it, which is not conducive to students' understanding and learning of Galileo's scientific thinking method and ingenious experimental conception in the study of free fall, and it is not conducive to students' independent learning.
