The device can realize dynamic co ordinate's rotation and dynamic direction at any angle to Kort force demonstration.

Description

technical field [0001] The Coriolis inertial force experimental device of the invention belongs to the technical field of physical mechanics experimental devices. Background technique [0002] Newton's laws of motion (including the resulting universal theorem of dynamics) apply only to inertial frames. For a non-inertial system, when an object moves in a non-inertial system, it will generate a Coriolis inertial force. As far as our earth is concerned, due to the rotation of the earth, the earth, as a moving reference frame, is a non-inertial frame. The Coriolis inertial force generated by the earth's rotation can explain many phenomena, such as the different wear of the two tracks of the train running north and south; the different degrees of scour on both sides of the river flowing north and south; The Coriolis inertial force has dual characteristics of "false" and "true". Its falseness is that it is not an interaction between objects, there is no force-applying object, a...

Problems solved by technology

The demonstrator can observe the phenomenon of Coriolis inertial force influence, but it can only demonstrate the Coriolis inertial force when the rotation axis z of the moving system is perpendicular to the moving direction of the moving point (the direction of belt movement) (that is, θ is 90°) Influenced phenomenon; only qualitative analysis of Coriolis inertial force, not quantitative measurement of Coriolis inertial force value

And as the turntable of the dynamic system, it can only change the direction of rotation, but not the angular velocity of rotation; it cannot be adjusted steplessly to change the speed of the belt.

[0006] In short, the above two devices can only demonstrate to students the phenomenon of Coriolis inertial force influence when the rotation axis z of the moving coordinate system is perpendicular to the moving direction of the moving point (that is, θ is 90° or θ is a certain angle); It is impossible to demonstrate the phenomenon of Coriolis inertial force influence when the rotation axis z of the moving coordinate system and the direction of motion of the moving point form an arbitrary angle (that is, the θ angle is variable), including being unable to demonstrate the rotation axis z of the moving coordinate system and the direction of motion of the moving point When parallel (that is, θ is zero), the Coriolis inertial force is zero; neither can quantitatively measure the Coriolis inertial force value
