AP Physics 1 and AP Physics C: Mech (Part 5: Free Fall) | Office Hours with Al

The plan for this stream was to continue with some kinematics problems involving horizontal motion, then introduce free fall. We then looked at several examples involving free fall. We'll be spending one more lesson after this to go over problems, then we'll be heading straight to projectile motion.

See the course plan here:
