Wednesday, April 8, 2009 - Block 2

Practice quiz on Newton's 2nd Law including coefficient of friction. Did not collect quizzes.

Handed out Problems in Newton's Laws problem sheet. Gave students time to work on it in class. Went over problem 11 with car in mud and explained how this worked with my fallen cedar tree.

Graded CD 5.1 while students worked on problems. Handed back graded sheets for correction.

Handed out worksheet on coefficients of friction. Did problem 5. Showed how pushing or pulling up decreases the normal force which then decreases the friction force. Related it to football.

Asked students to bring textbooks to class tomorrow.
