A Dynamically Variable Parabola Experimental Apparatus

Abstract

This patent discloses a dynamic and variable parabola experimental instrument, which is mainly composed of a flat square box for holding water, a motor, a power supply, a table and a mobile phone. Fixed in the groove of the turntable, one end of a lightweight straight rod is perpendicular to the water flat square box and fixed on the plastic turntable, and the other end fixes the mobile phone; the water flat square box is made of transparent resin board with holes on the top Flat square box, one side of the flat square box for water is engraved with a grid, put a certain amount of water and a little dyed kerosene into the flat square box for water, and insert a rubber plug into the hole of the square box to seal the flat square box for water; The water flat square box and the mobile phone rotate together with the motor at the same angular speed, and the liquid level in the water flat square box at the corresponding speed can be observed to explore the parabolic equation. The manufacturing cost is low, the production is easy, and the effect is obvious.

Description

technical field [0001] This patent relates to an experimental instrument for demonstrating a dynamic and variable parabola, which belongs to the field of university mathematical and physical experimental instruments. Background technique [0002] The concept of a rotating parabola is often used in college physics classes and advanced mathematics classes. Especially for college students who are beginning to learn mechanics courses, it is difficult to prove that the liquid surface of a rotating liquid is a paraboloid, and it is difficult to understand. The inventor of this patent is also A series of studies are given in the literature [1], but some corresponding demonstration experiments are lacking. The existing technology mainly uses the Newton bucket experiment to study. Due to the viscosity of the liquid, it takes a long time for the rotating liquid to reach the same angular velocity, and the observation is relatively Difficult, so far no better credible qualitative and qu...

[0002] The concept of a rotating parabola is often used in college physics classes and advanced mathematics classes. Especially for college students who are beginning to learn mechanics courses, it is difficult to prove that the liquid surface of a rotating liquid is a paraboloid, and it is difficult to understand. The inventor of this patent is also A series of studies are given in the literature [1], but some corresponding demonstration experiments are lacking. The existing technology mainly uses the Newton bucket experiment to study. Due to the viscosity of the liquid, it takes a long time for the rotating liquid to reach the same angular velocity, and the observation is relatively Difficult, so far no better credible qualitative and quantitative demonstration experiments have been given for this problem. How to achieve rich demonstration content, obvious visual effects, and credible demonstration experimental equipment, this patent will solve this problem
