Reviewing

We started reviewing ideas today in preparation for the exams at the end of the week. Honors Physics and Physics D worked additional problems involving the force of friction, net force, and acceleration. Students had to determine the values for the normal force and friction, in order to calculate net force and acceleration and Honors Physics, especially, had to work with kinematics to solve their problems. We'll go over any last bits of this tomorrow before starting our review for Thursday's exam. Physics F used their static and kinetic friction lab to highlight our discussion about friction. We looked at why static friction (maximum) is larger than kinetic friction and how the normal force and coefficient of friction play into friction calculations. We ended the class by working on a couple of problems involving friction and an object's motion and we'll go over those tomorrow before starting on our review for our exam. On Friday, all these folks start our next unit - Work and Energy.

Intro Physics discussed their lab on projectile motion and addressed any lingering questions about the calculations or assumptions we made to accomplish those calculations. We then started on a series of practice problems involving projectile motion, net force, free-fall motion, etc. as preparation for Friday's exam. Tomorrow we'll do some tying-up of loose ends before taking a look at Newton's 3^rd Law of Motion, the last bit of this chapter's information that's on Friday's exam. We'll save the momentum piece for it's own unit.
