Day 104: Solving Energy ProblemsPosted: February 26, 2013
Today was the first day of solving problems with energy beyond energy bar charts (meaning, using K=1/2mv^2, etc). Anecdotally, I think that doing energy bar charts first qualitatively, plus starting energy empirically, has significantly increased students understanding of work and energy transfer. Thus problem solving today was a breeze. I should have some data on this in the future.
