QUIZ Today on Archimedes' Principle!

After the quiz, we'll test our penny boat designs and see how close you came to your predictions.  Don't forget to include this information in your lab write-up due tonight.

Homework:  Finish penny boat lab and submit through Google Classroom.  Watch pre-lab video below to review how to solve work/energy problems - Chapter 8 #27.  The important thing in this video is to make sure that you understand how to make a "before & after energy diagram."  This method of solving energy problems is not something that is universal amongst physics teachers, but I do think that it is helpful and virtually foolproof, so I would like to see you use it.  In addition, you should be able to use the conservation of energy equation to solve energy problems.  This method is different than the "Work-Energy Principle" method, so you might want to also look that up in your textbook (p. 165) and understand how it differs from the "conservation of energy" method.  Both methods work, but given the situation, one usually works better than the other.  Figure out why.
