Parent-Teacher Conferences tonight and tomorrow, so make sure to be very polite at home to buffer "the talk" you'll get when your parents come home afterward...

Honors Physics embarked on a study of rotational motion. The nice thing for this first piece is that the topics are familiar - displacement, speed, acceleration, kinematics - they just have a slightly different twist. Once you orient yourself as to how to define angular displacement, the rest is easy. Tomorrow, we'll look at how angular motion and linear motion affect each other and also add in a third acceleration value - centripetal acceleration - which is what promotes the circular motion to begin with.

Physics B reviewed their Machines and Efficiency math packet and addressed any final issues before tomorrow's exam. Physics F, on the other hand, conducted two lab investigations centering around conservation of energy. The motion of a basketball tossed into the air was used to corroborate conservation of energy and conversion of energy between kinetic and gravitational potential forms. A second experiment with a mass-spring system focused on kinetic and elastic potential energy. Some groups still have a bit to do on that last one, so there will be time provided in class on Monday to complete the work.

Physical Science reviewed their MCAS practice material for forces, laws of motion and momentum until they were called down for Peer Mentors. We'll continue to review the packet on Friday and start a general review of the material for this unit looking towards Tuesday for the unit exam.
