Relative Velocity

Bellwork is was a small half-sheet called ESA Practice: Vector Components. We used it to review yesterday's material and to look at the Evaluating Student Answers category of question, which will show up repeatedly in the future. You did not turn in this little paper.

Later we talked about relative velocity. There aren't a lot of notes; here is what ended up on the board first period:



Mythbusters did a pretty cool experiment showing the forward velocity of a truck cancelling out the backward velocity of a cannonball so that the velocity of the cannonball relative to the ground was zero: Mythbusters Frame of Reference.

Section 3.5 in the textbook also talks about this, albeit with a lot more math than we used.

Homework is in two parts tonight:

A.) Kinematics TIPERs #4 (email miss.volkening@gmail.com for a copy)
B.) p.82 #41 & 44

Please note that this means you will be turning in two different things tomorrow.
