Day 93: The Start of the Energy Transfer Model

2014-02-28 08.39.58

Today we started the Energy Transfer Model. The first day I copied from Kelly. The students above are at the point of trying to find spring displacement values such that the carts will be launched with the same area under the F vs x graphs. Below is at first when the students are tying to find positions such that the forces acting on the springs are the same (which awesomely leads to the weaker spring launching the cart faster!) After this I continue for a couple more days by empirically exploring how work affects a couple different situations.
