Rotational Motion
A popular topic in Physics is the study of rotational motion. Create a world with at least four objects (such as a compass, mailbox, mantle Clock, and tire). Create a realistic rotation method for each object that has the object rotate one full revolution and then perform some other action. For example, if one of your objects is a compass, make the compass needle spin around quickly in one direction and then spin around again in the opposite direction. Add events that will call the rotational motion method for an object when the object is clicked. (If the world has four objects, four events will be needed.)
