Our rotation test will be next Wednesday. (After that we will spend a short time studying gravity and the motion of the planets. Scores from this material will be added to the rotation unit.)
When we looked at linear motion we discussed- kinematics (description of motion), dynamics (forces and causes of motion), energy (a conserved quantity) and momentum (a conserved vector quantity).
So far in rotational unit we've looked at kinematics, dynamics and energy... that must mean today brings us angular momentum.
