What is gravity, why is it important, and why can't we live without it?

Gravity is the pull of the earth. We cant live with out it because it holds us to earth and holds are air.

Gravity is the force that is pulling us down and keeping us on the ground. It is important becuase if we didn't have gravity then the water would be floating and we would be floating to. We couldn't plant crops or get food becuase nothing could grow if it is floating. That is why we can't live without it.

gravity is the pressure 9.8meters squared pushing us down to the earth. If we didnt have it we would float around and then we would float to space where we cant breathe and then that wouldnt be good.

Gravity is the force that is between two any objects. We need it to live because or else we would float around. We need it for everything that we need to live and survive.

Gravity is escincial to our earth and keeps our earth functioning with out it it would be impossible to drive a car or much else. What gravity is is a force that pushes us down and is different from planet to planet for earth the gravity is 9.8meters per2inch of pressure that is pushing down on us.

Gravity is the force that the earth has the keeps us on our feet. If we didn't have gravity we would float off into space and we wouldn't survive. In pressure gravity is 9.8 meters sqared. Also if we didn't have gravity the moon would float away and we wouldn't have a moon anymore.

Gravity is the force that keeps planets together. It is important for us, because without gravity, we would not have anyway to stay on the earth and not float away into space. We can't live without it, because without gravity our cells are not able to function properly.

Gravity is an attractive force between any two objects that depends on the masses of the objects and the distances between them. The force increases as the mass of either object increases, or as the objects move closer. Gravity is very important because without it us/ and everything else would be foating around because there would be no force pushing us/ them to the ground. I think that it would be fun not to have any gravity for one day!! That would be fun!!

Gravity is the natural force of attraction exerted by a celestial body, like Earth, upon objects on or near it. It draws them to the center of the body. This means that it holds us and everything we have on earth. Gravity pulls us towards Earth's center. It would be impossible to do anything! Without gravity, we would float around and eventually die. We can't breath in high atmospheres, we wouldn't get food, we couldn't drink water, etc. Nothing would be on earth. We can't live without plants and shelter. Water, trees, etc. would be flying around and could hit you!

Gravity is the force that all objects exert on each other. But the larger the mass the more gravity it will have. Life without gravity it would be very bad. Becuase without gravity it would be almost impossible to build buildings. That and we wouldnt be able to grow food very easily.

Gravity is the force of attractionby which terrestial bodiestend to fall toward the center of the earth. If we didn't have gravity we would all float and we couldn't breathe because of it.
