Experimental device for learning coriolis force and Foucault's pendulum

摘要

The present invention reproduces the facts of earth's rotation in the laboratory so that the concept and principle can be accurately understood, and at the same time, it presents various variables in the process of experimenting to develop scientific thinking ability and inquiry ability, This invention relates to a forward force and Foucault pendulum experiment apparatus to understand the principle.;In order to achieve the above object, the present invention provides a rotary device 200 by a variable motor M on the bottom plate 102 of the case body 100, and the rotary disc 300 on the rotary device 200. Installed and rotated by the variable motor (M), and the first, second, and third launcher (316, 318, 320) at three different positions of the target paper 312 on which the latitude and latitude are displayed on the rotating disk 300, respectively. ), And the pendulum 334 is connected to the holder 332 provided with a release device in the center of the bracket 326 installed across the rotating disk 300 by a connecting line 336, the bracket ( On the holding rod 328 on one side of the 326 is installed oscillation table 340 for quietly operating the pendulum 334 without shaking, the variable motor (M), the first, second, third launcher 316 (318) 320 and the oscillator 340 are electrically connected to the operation switch of the control nameplate 110, and at the same time, the positioning switch and the rotation angle of the southern hemisphere and the northern hemisphere are adjusted. Is a hayeoseo a switch, respectively.
