Example Exercise

Assignment

Why do tides occur on the side of earth opposing moon and why are the tides on both sides not equally high?

Note for teacher

For solving this exercise it is not necessary to change the semi-major axis of moon's trajectory. To keep the number of parameters as small as possible all buttons which are not needed should be hidden. In order to do this and to set up the initial conditions for this exercise, the following JavaScript code is executed upon loading of this web page:

function initialize() {
     simulation.jsSetVisible("no","Zoom");
     simulation.jsSetVisible("no","Reset");
     simulation.jsSetVisible("no","Distance");
     simulation.jsSetDistance(60000);
     simulation.jsSetEccentricity(0.5);
     simulation.jsZoomIn();
     simulation.jsStart();
}
