Forces may change the shape of an object. An elastic object, such as a spring, stores elastic potential energy when stretched or squashed. The extension of an elastic object is directly proportional ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

I blame Destin and his interesting sling shot video. Watch it. In this video, he claims that rubber bands do not act like springs. By "acting like springs" of course he means Hooke's law. This ...
