Collected Air Resistance Labs - Had students make sure they had their names, partner(s) names, Title of Lab, and date.

Collected, graded, and handed back CD 5.1 for those that turned it in. These are do for the last time next Thursday

Content Objectives:
Student will be able to:
. Correctly draw free-body diagrams for "complicated" situations
. Use the problem solving strategy to solve Newton's Laws problems with inclined planes and coefficients of friction

Homework: at a minimum, do problems 3,7,8,9 on the Newton's Laws - Practice Problems worksheet

Handed out Free-Body Diagram worksheet. Students worked on it and then we went over it in detail as a class

Handed out problem solving strategy guide sheet for Newton's Laws

Solved a problem using the problem solving strategy. A block started at rest and slid down an inclined plane with friction. Given the mass, angle of incline, distance it slid down, and coefficient of friction, we solved for the time it took and the speed at the bottom.

Handed out two worksheets with problems on Newton's Laws: Newton's Laws - Practice Problems and Applications of Newton's Laws.
