which force is helping to stay the earth on its orbit?

Answer 1

The space being empty and nothing and being one without any direction or up or down there is no po question of any body falling anywhere from its position .all bodies are in movment in the direction in which they got a thrust intially from the explosion tha caused them to scatter around .since massess have a force of attraction , those small bodies tha are caught in the field of gravity of any bigger mass are subject to two forces , that is its movement in a straight line in the direction of the thrust it got got initially and the force of gravity that pulls it towards the center of the biger body.the distnce between the biger body and the one that is drawn by it being enormous , the smaller one does not fall into the bigger body but moves along the direction of the resultant of the two forces acting on it and this keeps the smaller one in an orbit around the bigger one .the gravityof he sun and the direction of the movement of the earth help to keep it in equillibrium in an orbit around the sun.The direction of the movement of the earth is a centrifugal force that throws the earth away form the sun and the gravity of the sun draws the earth towards itself and the planet finds a path along the resultant of these two forces and this keeps the planet earth in an orbit around the sun and this causes the creation and the existence of life on this planet .

Answer 2

Gravity keeps the earth in orbit around the sun - the cintripital force is a result of the gravity.

Answer 3

Centrifugal and centripetal forces.

It is, but slowly and surely moving towards the sun.

This is because, centripetal force is only slightly more than the centrifugal force.

Centripetal Force:
This is the net effect of gravity(it is the pull towards the Sun).= P.

Centrifugal force:
Moving of Earth mainly along the elliptical orbit around the Sun( it is the pull away from the Sun) = F

P > F By slight amount.

So how much have we moved in ten million years?:

In to-days time frame it would have taken 20 months to do the journey around the sun on a much Bigger elliptical orbit.

In other words.

In to-day's time frame we would have taken 20 months to go around the sun instead of 12 months.

Other facts:

We are also slowing down.

Earth use to take only 20 hours to complete a revolution in to-day's time, we take 24 hours to do the same thing. The days got longer by 4 hours over 10 million years.

Answer 4

Due to the speed the Earth is travelling through space, it is always trying to travel in a straight line.

Due to the enormous gravity of the sun, it is trying to pull the Earth towards it.

The motion of the earth and gravity of the Sun balance out and place Earth in a circular (ellipticle in reality) orbit around the Sun.

Answer 5

The earth's orbit is a balance between the sun's gravitational force and the inertial force (centrifugal force) that tends to move it in a straight line.

Answer 6

The force of gravity generated between the earth and the sun.
Centripetal and centrifugal forces.

Answer 7

Gravity

Answer 8

Science call it GRAVITY, but on the other hand it may be GOD also.
Till today GRAVITY gets the most vote, but after maybe 200 years, new force n laws may be discovered ('cause it's an infinite holographic universe, u know..) and then GRAVITY may get a big "Booooo". Ur great great grandson may be asking YAHOO ANSWER...."what WAS gravity?"......

Answer 9

the sun's gravity keeps it in orbit

Answer 10

Centripetal force
