The On-line  Pulley Experiment.

This experiment may be reported to Mrs. Mack or Miss Walker in one of two ways. Two methods are provided in case your browser does not allow one of them. In both cases you will be using an applet from the site of Walter Fendt in Germany, who has made some very nice applets. In return you will receive a Freddo.

Half-size the window by clicking on the middle of the top right buttons (next to the x)
