Khan Academy: Newton's Law of Gravitation: Would a Brick or Feather Fall Faster?
Presents an analysis of a problem where a brick and a feather are dropped on the moon to see which would hit the ground sooner. This is compared to the gravity on the Earth, where the air resistance on the objects would produce a...
