科里奥利力 (2).png


科里奥利力

       接通电源,观众按下电钮,皮带轮开始旋转,30秒后大底盘开始旋转,观众将可以看到与普通惯性力和惯性离心力不同的科里奥利力现象。
       相对于地球运动的物体由于受到地球自转的影响原来的运动方向就会发生改变。弹性编织带的运动就相当于在地球上运动的物体,大圆盘的转动就相当于地球的自转,由编织带的运动和大圆盘的运动一起产生了科里奥利力,使两条编织带的位置发生了变化,由相互平行变化成了彼此靠近。
       自然界有许多现象都会受到科里奥利力的影响,如发射炮弹、火箭、台风的移动轨迹等等。


Coriolis Force

       Switch on the power. The spectator pushes the electric button, and then the pulley begins to rotate. After 30 seconds, the big chassis starts to rotate. Then the audience can see the phenomenon of Coriolis force, which is different from the common inertia force and inertia centrifugal force.
       Because of the influence of earth rotation, the former movement direction of the object, which moves relative to the earth, will be changed. The movement of elastic woven strip is equivalent to the moving object on the earth. The rotation of the big round disc is equivalent to earth rotation. The movement of woven strip and the big round disc together create the Coriolis force, which makes the positions of the two woven strips change from being mutually parallel to mutual approaching.
       Many phenomena in the nature are influenced by Coriolis force, such as cannon shooting and rocket launching and the moving track of typhoon, etc.
