So far we've only talked about situations where energy is conserved - that is, there are no outside forces. Today we talked about what happens when there are outside forces - the momentum changes! This change in momentum is called impulse.

Video we watched
Next class you will be making a device to save an egg from breaking after a fall from the visitors' bleachers. You need to bring your own supplies if you can since mine are limited. It would also help if someone in your group brought an egg. After we test your device you will turn in a short explanation of why your egg did or did not survive using momentum concepts.
Homework for the weekend is Chapter 6 (p.191 ) Problems #9, 11, 13 + CONCEPTUAL Problem #12 (p.190)
