Day 97: Planning for the Energy Transfer ModelPosted: March 12, 2014
Today I finished up my packet for ETM, as always heavily borrowed from Kelly’s materials. I also added an introduction to energy bar charts that drew upon how I start the energy unit by summarizing the demonstrations and experiments that start the unit (described in detail here). Secondly, as shown above I wanted to add some problems where students had a force that varies with position and find the work done, and hence the energy transferred, by manually finding the integral. I like that this is closer to the definition of work as int(F dot dx), and that it doesn’t force (hehe) us to only deal with constant F situations.
