i am 6yrs old and would like to know how does gravity work on earth.?

Answer 1

Gravity is like a tug, when you play tug of war. Your best friend pulls on a rope and you pull on the other end. That pull, the tug, is like gravity. Only the Earth is your best friend pulling on you with something called the force of gravity.

The force of gravity is invisible, unlike the rope. But it is still a force just like the tug on a rope is a force. In this case, the tug by the Earth pulls you back to the ground every time you jump up. It also pulls you down the slide in your favorite playground. Earth is a very strong friend and keeps tugging at you all the time.

Like Earth, all the planets and stars tug with their own forces of gravity. So even if you jumped up on the Moon, the Moon would tug you back down to its surface. But the Moon is much smaller than Earth and not as strong as Earth; so the Moon's tug is not nearly so strong as Earth's tug would be.

The tug from gravity is commonly called weight So if you weigh 60 pounds, that's because Earth is tugging on you with a gravity force of 60 pounds. Because the Moon is smaller and weaker than Earth, you would weigh only 10 pounds on the Moon even if you weighed 60 pounds on Earth. And if you were out in space, nowhere close to a planet or a star, you would weigh almost nothing because you would be so far away from the tug, the force of gravity, of any planet or star.

Good question.

Answer 2

Everything in the universe pulls on everything else, something like two magnets pull on each other but not nearly as strong as that. The closer two things get to each other, the stronger they pull on each other. The heavier the things are, the stronger they pull on each other. For regular objects that you can find in a room, this pull is much too weak for you to notice it. You would need special instruments in a science lab to measure the pull on something even as heavy and as close to each other as two balls made of lead.

The earth is very, very big and heavy and it is close. The earth can pull a lot stronger than anything else near you. When you pick something up, you are in a tug-of-war with the whole earth, and if the object is light enough, you are winning as long as you hold the object. But if you let go of the object, the earth will still pull on it and it will drop to the ground.

Answer 3

We think there is a bunch of little itsy bitsy particles zipping around which when they hit anything give it a little pull.
Everything that you can touch (not light or moonbeams!) gives off these particles (Higgs Bosons, they are called)
The bigger something is the more of these it gives off.
So the Earth, being HUGE gives off a lot and pulls us down to its surface. Everything is pulled at the same speed. Bigger things are pulled more, but there is more of them to pull and so they fall at the same speed as small things. Things like feathers are pulled at the same speed as rocks and airplanes, but air can get in the way. Feathers float down slowly and planes can use air pressure to keep from falling, and rocks fall pretty fast. When something falls to earth, the earth falls a little bit towards the something, they fall together. Its way too small for us to see, feel or measure.
We'd only notice it if it were as big as the moon or an asteroid. (This is different than if Earth got HIT with a asteroid or comet - that huge disaster would be caused by the energy of the crash). Finally, as objects fall they go faster and faster. This is called acceleration and things accelerate until air resistance balances the speed.

Answer 4

The large mass of the earth pulls all objects on the earth towards it, the larger the mass of the object the greater the pull.

Answer 5

the force of the mass created on earth pulls you in which make gravity

Answer 6

Wait 6 yrs. Then you will get the answer.

Answer 7

I'm more than 6 and would like to know that too. If you find out let me know.
