Handed back Air Resistance Labs. Went over and answered questions.

Compared and contrasted contact friction and air resistance.

Answered questions from WebAssign.

Showed the rest of the Hewitt video with emphasis on why when you drop two different masses they will hit the ground at the same if air resistance is negligible and the idea of air resistance.

Handed out Problem Solving strategy sheet.

Handed out Newton's Laws Practice problems. Students worked on them in class. I supplied an answer key.
