 Title: Coriolis effect Post 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 effect Post by: lookang on February 12, 2018, 12:03:34 pm I have recreated a JavaScript version of this simulationhttp://iwant2study.org/ospsg/index.php/interactive-resources/physics/02-newtonian-mechanics/05-circle/623-coriolis2denjoy! Title: Re: Coriolis effect Post by: lookang on February 18, 2019, 02:40:11 pm 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); // differentiatevy3=vy-y*w*Math.sin(c)-vy*(1-Math.cos(c));Then the rotation is correct Title: Re: Coriolis effect Post by: Fu-Kwun Hwang on February 19, 2019, 06:29:09 pm Very good. Thanks! :D
