We began class with a review from yesterday by demonstrating the relationship between kinetic and potential energy. I used a pendulum hanging from the ceiling to complete the activity on page 11-16 as students realized their relationship. I discussed the differences between internal and external combustion engines (Section 11-3 notes). We worked on page 11-11 collectively, as I pointed out that velocity has a greater effect on kinetic energy than mass does because you need to square the velocity. Finally, students worked within their groups to complete worksheet 11-9, and volunteers put the answers to those problems on the board before the end of the period.
No homework was assigned, and the Chapter 11 test will be on Wednesday, April 20th.
