Period 7- 11/24

The first thing we did today was take our 4th re-assessment on vectors. One question had to do with the "Angle of Attack" of a helicopter. You can read more about that subject here; http://www.copters.com/aero/angle_of_attack.html

Next we started to go over the lab. One of the big ideas that we found was that Gravitational Force = Mass x Gravitational Field Vector. Also, we found through our testing that there are 10N for every Kilogram.

After we dove into these ideas, we got into a discussion about elastic forces and the differences in force between small springs such as springs from a pen or a slinky, and also, large springs such as the shocks on a car.
