Rocket Trajectory Quiz.
Went over quiz

IB Projectile Motion Rocket Quiz.
Went over quiz

Handed back CD 3.2, first rocket projectile quiz, analytic addition of vector quiz.

Showed the rest of the Hewitt video on Vectors and Projectile Motion. Explained why objects in free fall are "weightless" even though there is a force of gravity on them. Astronauts in the space shuttle appear weightless because they are falling around the Earth.

Hit the Bar write-up due Friday
Test on Projectile Motion next Tuesday.
