Embodiment Construction

[0017] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0018] As shown in the figure, an experimental device for exploring and demonstrating the momentum theorem includes a base 1, a bracket 2, a support for a collision weight 4, and an impulse measurement circuit, the bracket 2 is fixed on the base 1, and the collision weight 4 Hanging on the support 2 and can swing back and forth, the impact measuring circuit is used to measure and display the force on the support when the collision weight 4 collides with the support.

[0019] The collision weight 4 is a sphere, a cylinder or a cube, and the surface of the collision weight can be wrapped with a detachable soft layer.

[0020] The impact gauge also includes a dial 5 fixed on the support 2, and the dial 5 is used to display the angle of the collision weight 4 deviating from the equilibrium position.

[0021] Described impact meter comprises po...

Abstract

The invention discloses an experimental apparatus for exploring and demonstrating the momentum theorem. The experimental apparatus comprises a base, a support, a collision weight, a supporting object and an impact force measuring circuit. The support is fixed on the base, the collision weight is hung on the support and can oscillate back and forth, and the impact force measuring circuit can be used for measuring and displaying force born by the supporting object when the collision weight and the supporting object collide. The experimental apparatus is simple in structure, low in cost, simple in operation, obvious in effect, and capable of helping students to visually understand the momentum theorem and enriching teaching content and teaching methods, and materials can be obtained easily.

Description

technical field [0001] The invention relates to a teaching tool, in particular to an experimental device for exploring and demonstrating the momentum theorem. Background technique [0002] "Momentum theorem" is a very important key content in physics mechanics. It is more widely used than Newton's law of motion. However, no manufacturer has produced an experimental device to explore or demonstrate the momentum theorem. During the teaching process, teachers basically use The momentum theorem is derived through theoretical derivation. Contents of the invention [0003] In view of this, the purpose of this invention is to provide a kind of experimental device for exploring and demonstrating the momentum theorem. [0004] The purpose of the present invention is achieved through the following technical solutions: [0005] An experimental device for exploring and demonstrating the momentum theorem, including a base, a bracket, a collision weight, a support and an impulse measu...
