Скачать или смотреть Bungee Drop

In AP Physics Class today, students predicted how far a bungee cord would stretch when an attached mass was dropped from a known height. The little blue car on the filing cabinet is the predicted maximum position.

To do this students built a 'bungee cord' out of rubber bands. They then used a force probe and motion sensor to determine the spring constant, k, of their rubber band bungee.

Students used the conservation of energy to predict how far the bungee would stretch. It was a lot of fun.

If you are interested in the physics of this endeavor please see the following for pictures of the set up and a .pdf of the derivation. As well as a spreadsheet model of the situation.
