Introduction to Gravity00:00:05

Gravity is an invisible force that pulls objects back to Earth, preventing us from floating off into space.

Isaac Newton's Discovery00:00:25

About 300 years ago, Isaac Newton discovered gravity after observing an apple fall from a tree and wondering why it fell down instead of up.

Mass and Gravitational Pull00:00:52

Every object with mass exerts a gravitational pull on other objects, with the strength of the pull depending on the mass of the objects.

Gravity in Space and Earth00:01:11

The sun's gravity keeps planets in orbit, and Earth's gravity keeps the moon from floating away.

Tides and Weight Differences00:01:37

The moon's gravitational pull causes ocean tides, and because the moon's gravity is one-sixth of Earth's, objects weigh significantly less there.
