Common exam II will take place the FIRST MONDAY AFTER SPRING BREAK Common exam II will take place the FIRST MONDAY AFTER SPRING BREAK. Sorry…. Schedule set by Registrar’s Office, not Physics Dept. Exam II will cover chapters 4, 5, 6, and 7. TODAYs Material and NEXT WEEK’s material WILL be covered on the exam. Next week, I will be out of town at a Scientific Conference. Professor Zhou will be giving the lecture. I will be available via email if you need me.

Iclicker Question #1 In which of the following scenarios am I NOT doing work? Pushing a box up a frictionless incline. Pushing a block up an incline with friction. Moving a box from the table to the floor. Carrying a heavy box across the room. I am doing work in all of these examples

Iclicker Question #2 In which of the following scenarios am I NOT doing work? A B C D B and D

Scalar or Dot product Calculates ‘product’ of vectors which are parallel to each other.

Iclicker Question #3 Calculate if 24 1 k 1 -24 None of the above

Work done by Spring

Is the kinetic energy derived from the work done by gravity accurate? http://www.lghs.net/ourpages/users/dburns/RRPhysics/Road_Runner_Physics/Movie_files/RollingBoulder.mov
