Title: Coriolis effectPost by: Fu-Kwun Hwang on June 15, 2013, 11:13:48 am
In physics, the Coriolis effect is a deflection of moving objects when they are viewed in a rotating reference frame. In a reference frame with clockwise rotation, the deflection is to the left of the motion of the object; in one with counter-clockwise rotation, the deflection is to the right.
The following simulation help you visualize the Coriolis effect! Click the following image to show the simulation. [eye][ejsapplet][/eye] Title: Re: Coriolis effectPost by: lookang on February 12, 2018, 12:03:34 pm
I have recreated a JavaScript version of this simulation

Dear Prof Hwang,
I think I fixed a bug //x3=x-y*Math.sin(c); //Rotating with Disk Viewpoint apparent trajectory //y3=y-y*(1-Math.cos(c)); x3=x+y*Math.sin(c); //Rotating with Disk Viewpoint apparent trajectory MUST change to + instead of -y3=y-y*(1-Math.cos(c)); //if(y<-R)_initialize(); if(y<-R)_pause(); // added pause by lookang //vx3=vx-y*w*Math.cos(c)-vy*Math.sin(c); //vy3=vy-y*w*Math.sin(c)-vy*(1-Math.cos(c)); vx3=vx+y*w*Math.cos(c)+vy*Math.sin(c); // differentiate vy3=vy-y*w*Math.sin(c)-vy*(1-Math.cos(c)); Then the rotation is correct Title: Re: Coriolis effectPost by: Fu-Kwun Hwang on February 19, 2019, 06:29:09 pm
Very good. Thanks!
