Yesterday, due to pictures, you started reviewing for Friday's final

Today, the test....finally.

Objective:  SWBAT demonstrate their knowledge of work, power, and work-kinetic energy theorem on a test.

Warm Up:  Pick up the equation and constant sheets.  Pick up a scantron.
Date:  12/13/11   Subject:  W,P and W-E Theorem test.

12/9

For the last 3 days we have been "work"ing on a lab that is due Monday.

Objective:  SWBAT review for Monday's test on work, power and the work-energy theorem.

Warm Up:  A child pushes on a box of mass m which moves with constant speed v across a hroizontal floor.  The coefficient of kinetic friction betwen the box and floor is "mu".  At what rate does the child do work on the box?

12/5

Objective:  SWBAT determine the work that friction does on a block to stop it from moving.

Warm Up:  Pick up a lab packet.  Get into your group.  Silently pre-read the first page.
