Day 22: Longest Day of the Year

I talked so much today. Even though we have shortened periods this week for Spirit Week, everyone agreed that today seemed long. Lecturing is boring.

I didn't know how else to show how the interaction diagram can be used to show where the energy is stored and how it is transformed. We did energy pie charts today, and it caused a real debate. We came to the conclusion that both the normal force and the force of friction could cause energy to transform into dissipated energy. On to energy bar charts tomorrow!
