Watch the videos below, and examine the yellow Total Energy bar.
* You only need to watch the first 30 seconds or so for No Friction - just enough to be able to make some observations. For the Friction Track, watch at least until about 1:35.
Track with No Friction:
Track with Friction Added:
What do you notice about the total energy? (You can even play both videos at the same time if you want to compare.)
