Collected Air Resistance Labs.
Went over friction worksheet - did all problems.
Went over problem solving strategy for Newton's Laws.
Two Interesting Problems with Real Life Applications:
1. Showed that if you push up on an object, the normal force decreases and the friction force decreases. Useful for football linemen.
2. Pulling car out of the mud problem.
Started Hewitt video.
