Collected Air Resistance Labs

Reviewed Friction lab in detail. Reviewed the concept of coefficient of friction.
Compared factors affecting contact friction to factors affecting air resistance.

Showed how to determine coefficients of friction by raising a board and seeing at what angle the object begins to slide and then at what angle it continues to slide with constant velocity.

Did a problem in calculating coefficient of friction and using the problem solving strategy for Newton's Laws problems.

Watched last part of Hewitt's 2nd law video, the part on air resistance.

Went outside and threw boomerangs for the last 15 minutes of class.
