Abstract

The invention discloses an observation device of simple pendulum movement and a record method of a simple pendulum movement track. The observation device comprises a cross rod, a rope, a pendulum bob and an observation platform, wherein one end of the rope is tied to the cross rod, and the other end of the rope is connected with the pendulum bob; the pendulum bob is suspended above the observation platform; the pendulum bob is internally provided with an emitter; and the observation platform is internally provided with a receiving controller, and the top surface of the observation platform is provided with a display screen which is electrically connected with the output end of the receiving controller. The movement track of a periodic pendulum is recorded through an electronic induction technology, an observer is led to understand the basic law of the pendulum through analysis on a track image, and simultaneously the characteristics of various pendulums such as Foucault pendulum, compound pendulum, torsional pendulum and the like and applications of the pendulums in production and life are further learnt.

Description

technical field

[0001] The invention relates to an observation device for realizing the movement of a simple pendulum and a method for recording the movement track of the simple pendulum. Background technique

[0002] The development and research of the pendulum are closely related to the development of the watch timer. The famous Italian mechanics Galileo first studied the simple pendulum, and later the Dutch scientist C. Huygens studied the compound pendulum, and they laid the foundation for the mechanical theory of the pendulum.

[0003] A pendulum is a mechanical device capable of swinging, which can be used to display various mechanical phenomena. The most basic pendulum consists of a rope or rod, and a hammer. The hammer is attached to the lower part of the rope, and the other end of the rope is fixed. When the pendulum is pushed, the hammer moves back and forth. People can see the motion of the pendulum, but not the trajectory of the pendulum. Contents of the in...
