Why does earth not fall down even though it is hanging in space?

Question

any object thrown will fall down due to gravity,but the earth stays in its place without falling, Why?

Answer 1

The earth is not hanging in the space. There are so many factors that effect the earth to be in the place she is. Any body of mass has a gravitational force. And there is a gravitational force between any two bodies. (It is not I who said this but Newton!!)

this force is directly propotional to the masses of the bodies and inversly propotional to the square of the distance between the two bodies.

Therefore, the force between the sun and the earth pulls the earth towards the sun and the force created by the spinning of the earth around her axis and the gravitational force of the planet Jupitor with his huge mass, keeps the earth in her place. Never forget Jupitor, he is the lord of the solar system, that keeps plantes in their positions with out being swept away in to the deep space.

Answer 2

Sir Isaac Newton explained this concept in about the year1680. He said: suppose you climb to the top of a high mountain, and throw a rock off of the top. It will land somewhere down the side of the mountain, right? Then suppose you throw another one alot harder. It will land even farther away, right? The harder you throw, the farther it will land away from you. Suppose you throw it really, really hard, so hard that it's fall matches the curvature of the Earth. So as it falls, the Earth's curve also falls at the same rate. The object that you threw will just keep on falling, until it comes all the way around the Earth and you have to duck to keep it from hitting you in the back of the head!! This is what it means to be in orbit. So the Earth is always falling toward the sun, but it always misses the sun, and just keeps on falling and falling and falling. So does the Moon and the space shuttle and anything else that is in orbit. Does this help?

Answer 3

the earth isn't sitting close enough to a large mass who's gravity could suck it in. technically, the earth is constantly "falling" towards the sun, but because of the shape of our orbit, that fall is in a circular shape that will never actually bring us closer to the center.

think of swinging a ball tied to a string in a circle. the string is the gravity between the earth and the sun, pulling the earth towards the sun (or the ball towards you). The only force acting on the ball is the string, the only force acting on the earth is gravity. they both pull directly inwards and yet the earth goes around the sun and the ball orbits around you. that's the best way to describe it.

Also, to clarify your question, the earth does not fall "down" towards the sun, since there is no real thing called down since einstein came out with the theory of relativity, this is especially true in outerspace. The only reference we use for "down" is where gravity pulls towards the center of earth, and this isn't a single direction, since the earth is round anyway

Answer 4

There is no such thing as down in space. Things fall down on Earth because of gravity. The only gravity significantly affecting Earth is that of the sun. Because the Earth is spinning around the sun, the resulting centrifugal force keeps it from being drawn in. It is like a ball on a string.

Answer 5

Here on Earth, we define "down" as toward the center of the Earth, because that is the direction in which the Earth's gravity acts. To someone in China (assuming you live in the US), "down" is in face the opposite direction from what you perceive as "down". Therefore, it makes no sense to speak of the Earth falling "down," since the Earth cannot fall toward its own center.

Answer 6

the earth is not hanging in space. earth and sun have attractive forces which pull each other. but the sun being a large mass it pulls the earth towards itself. the earth utilizes this force of attraction to provide centripetal force for itself and rotate around the sun in an orbit. for example when someone is pulling u by our one hand u tend to revolve around the person so that u are at the same distance from the person.

Answer 7

see u know newton's gravitational force that is the reason that earth remains in space and doesn't falls down because the force of sun and other planets who's gravity force don't allow earth to fall

Answer 8

Any object thrown up will fall to earth . But where does earth fall.It falls to sun consistently but always fails because it goes around the sun

Answer 9

Things fall down when gravitational force of the obect which is cause of it is much more than any other force. When forces are more than one the body moves by the action of resultant of all forces acting on it. In the solar system there are many planets which are attracting earth. The force of attraction is proportional to M*m/square(d) where M and m are masses and d is the distance. The forces acting on earth are such that they cause it to move in a path called its orbit and also result in its rotation. This is because other objects which are having their influence (force) are moving themselves for similar reason.
