Hi folks,
Today I introduced the concept of force diagrams also known as free body diagrams. We worked on them a bit in class and this week's homework will ask you to work on them a bit more. We also did a fairly complex lab asking the students to use their formulas and math skills to determine several aspects of a catapult.
For homework this week:
Finish the calculations in the lab if you haven't already done so in class.
Do the enclosed .pdf. Answers for the force diagrams are enclosed so you can check yourself.
