Relative Velocity

First we did a Plickers question instead of turning in last night's homework.

Then we looked at a TIPER where you had to evaluate students' statements about vector components.

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) - You will turn this in
B.) Suggested: p.82 #41 & 44 (won't turn in)
