Watch the videos found below, and then go to the link here Please draw force diagrams for Problems 1-15 on a sheet of paper (you DO NOT need to solve the diagrams, just draw them). You can probably just make copies of the web page, but there are lots of helpful hints up at the top. Hand in what you have done at the end of the hour.

Hooke's Law simulation
I have the flu :-( Justin and Ian, tomorrow you need to test your bridge, ok?
===
We are now moving from vectors and static forces (which don't move, or move at a constant velocity) to unbalanced forces (which have a lot more math, so you are going to need a calculator).
Today, you will study Hooke's law, which talked about movement of objects using potential and kinetic energy.
You can find the online simulation here
When you are finished, EACH person needs to post and individual paragraph in the comments section of the blog. Tell me about the difference between the forces and vectors that lead to kinetic energy, potential spring energy and potential gravitational energy.
Test is THURSDAY.
Congratualations to the football gentlemen for a TREMENDOUS EFFORT last night and good luck to the volleyball team tonight!
