Storyboard Text

  • ...And so that's how the brilliant Isaac Newton discovered gravity.
  • Yeah but how do you prove it?
  • Well, we can't technically prove it with the materials we have, but it's easy enough to explain why we think it exists.
  • If I drop this suitcase, it's going to fall to the ground. That's gravity's work. It's pulling everything down at 9.81 meters / second. The moon is another good example. Its mass is big enough so that earths gravity and the moons mass cancel each other out and in turn it gets stuck in orbit around the earth. The force of attraction between the two objects comes down to the mass of both of the objects as well as the distance between them.
  • That would seem to make sense. Gravity would both pull objects down and pull the moon into orbit.
  • I believe it. Everything seems to point to gravity being real.
