   How does gravity affect Earth?

   • Gravity is what holds the planets in orbit around the sun and what keeps the moon in orbit around Earth. The gravitational pull of the moon pulls the seas towards it, causing the ocean tides. Gravity creates stars and planets by pulling together the material from which they are made. Gravity not only pulls on mass but also on light.

   What does gravity do in physics?

   • Gravity is the force by which a planet or other body draws objects toward its center. The force of gravity keeps all of the planets in orbit around the sun. What else does gravity do? Why do you land on the ground when you jump up instead of floating off into space? Why do things fall down when you throw them or drop them?

   How does gravity work on Earth?

   • Earth's gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body. That's what gives you weight. And if you were on a planet with less mass than Earth, you would weigh less than you do here. Image credit: NASA You exert the same gravitational force on Earth that it does on you.

   How is gravity measured on Earth?

   • On Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth’s mass exerts on them. Gravity is measured by the acceleration that it gives to freely falling objects. At Earth ’s surface the acceleration of gravity is about 9.8 meters (32 feet) per second per second.

   Why is gravity important?

   • Much more significantly, it's a fundamental force between every bit of matter in the universe and every other bit: just like Earth and the Sun, you have your own gravity, and so do I. From Aristotle to Kepler and from Newton to Einstein, understanding gravity has challenged some of the best scientific minds in history.
