According to NASA 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. visit this link for further information.

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? The answer is gravity: an invisible force that pulls objects toward each other. Earth's gravity is what keeps you on the ground and what makes things fall.

Anything that has mass also has gravity. Objects with more mass have more gravity. Gravity also gets weaker with distance. So, the closer objects are to each other, the stronger their gravitational pull is.

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.

You exert the same gravitational force on Earth that it does on you. But because Earth is so much more massive than you, your force doesn't really have an effect on our planet.

Gravity in our universe

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. Albert Einstein discovered this principle. If you shine a flashlight upwards, the light will grow imperceptibly redder as gravity pulls it. You can't see the change with your eyes, but scientists can measure it.

Black holes pack so much mass into such a small volume that their gravity is strong enough to keep anything, even light, from escaping.

Gravity on Earth

Gravity is very important to us. We could not live on Earth without it. The sun's gravity keeps Earth in orbit around it, keeping us at a comfortable distance to enjoy the sun's light and warmth. It holds down our atmosphere and the air we need to breathe. Gravity is what holds our world together.

However, gravity isn't the same everywhere on Earth. Gravity is slightly stronger over places with more mass underground than over places with less mass. NASA uses two spacecraft to measure these variations in Earth's gravity. These spacecraft are part of the Gravity Recovery and Climate Experiment (GRACE) mission.

GRACE detects tiny changes in gravity over time. These changes have revealed important details about our planet. For example, GRACE monitors changes in sea level and can detect changes in Earth's crust brought on by earthquakes.

Do you know what gravity is? Firstly gravity is so very important to the universe and how the universe works. It's also very important to our planet, and how it works, and how humans function. Actually it's just really important period! And here's why.

Without gravity, our universe wouldn't function the way we know it to, and neither would Earth. If gravity didn't exist you would literally fall off the planet and float away into space, along with everything else. So gravity is a force of nature that is there, and is key to our planet and the universe.

Like Dark Matter, and Dark Energy, we cannot see gravity so how do we know that it's there? Well first of all, we can thank the well-known historical physicist Sir Isaac Newton for discovering gravity. It was this great mind who one day discovered that objects of Matter are not just on the Earth, that they are actually pulled down to the earth by a force discovered as gravity.

Gravity is a strong force of nature, but not so strong that it actually pulls absolutely everything down all of the time so strongly. That wouldn't work either. However it is a force that keeps everything in check and in balance, and keeps us grounded.

Like when Newton and that famous story as to how he discovered gravity - the Apple fell from the tree, however the Apple grew and was connected to the tree, and came off naturally, hitting the ground. So what that means is that objects of matter are pulled to the ground with mid force once they have become free.

So you can climb the tree and gravity will not pull you and the tree down to Earth, but if you come away from the tree and fall, you are gown down!!

So while gravity keeps us grounded on earth, it does something different with the planets, stars, galaxies and the whole universe. Gravity brings and binds everything together, all the way through the cosmos.

Think of gravity as like the glue that sticks to the Earth and the universe, and helps everything work. Gravity is so special, we cannot do without it. If gravity didn't exist it would be a very strange universe!

# 2. The tides in the oceans are governed by the gravitational forces of the Earth and its moon.

# 3. You would weigh differently on each planet than you would on Earth due to the different gravitational pull of each planet.
