Multifunctional inertia law demonstration instrument

Abstract

The invention discloses a multifunctional inertia law demonstration instrument. On the basis of a horizontally-installed substrate, the demonstration instrument is provided with a traction speed adjustable reciprocating linear traction mechanism, an ejection vehicle, a moving object inertia experiment mechanism, a static object inertia experiment mechanism and a liquid inertia experiment mechanism. The moving object inertia experiment mechanism includes an electromagnetic ejection apparatus, a plastic cup and a plastic ball. The static object inertia experiment mechanism includes a metal balllimit box, a metal ball, a sand holding box and a sand holding box supporting stand. The liquid inertia experiment mechanism includes a water holding box. The demonstration instrument overcomes the defects of a conventional inertia law demonstration apparatus, and can demonstrate that a moving / static object has inertia and that liquid has inertia. The whole demonstrate process is more direct.

Description

Technical field [0001] The invention relates to a physical experiment device, in particular to a multifunctional inertial law demonstration instrument. Background technique [0002] In physics experimental devices, especially those used to demonstrate the law of inertia, it is often necessary to demonstrate the law of inertia, which is Newton's first law of motion. We all know that Newton's first law of motion, referred to as Newton's first law. Also known as the law of inertia and the law of inertia. Common complete expression: Any object must maintain a uniform linear motion or a static state until the external force forces it to change its motion state. The statement in the Lujiao version of the high school physics textbook is: Newton's first law states that when the resultant external force is zero, the original stationary object will continue to remain stationary, and the original moving object will continue to move in a uniform straight line at the original speed. There ...

Problems solved by technology

Although this Newton's first law demonstrator can ideally demonstrate the law of inertia, students often do not feel the inertia of moving objects. In addition, its demonstration function is single. It can only demonstrate the inertia of moving objects and cannot demonstrate the inertia of stationary objects. There is inertia, and it cannot demonstrate that liquids have inertia
