Embed the Work Calculator
Work done by a force over a distance, with the angle between them, plus the power if it took a given time and the same figure in calories. Set the values it should open on, then copy the iframe. Your visitors can change them; the widget recomputes against Rule Calculator and never touches your page.
Opening values
Set what the widget shows before anyone touches it. Leave a field as it is and it stays out of the URL.
