When Sun and Earth are attracting each other why do Earth not fall on
Sun.


When we throw a big Stone in air It will Fall Back on Earth.
Simmilarly For Sun Earth is just a piece of Rock? Who do this big rock
Earth Fall onto the Sun Just like the Stones which we throw in air
just come back and hit the Earth?

Simmilarly why not the Moon fall on Earth by the Gravity attration?

Why are the planets revolving round the sun for so many years instead
of just falling onto the Sun?

When we visit Moon on a Rocket Our Rocket Just Falls on Surface of
moon So why these heavenly bodies not falling on Bigger one?

Actually Newtonian physics say something similar: mass dictates
gravitational force (upon another mass) and in turn, the gravitational
force dictates how mass moves by the reaction of that gravitational
mass (third law).

There is nothing wrong with both sttatements. They produce wonderful
models of gravitational effects although they do not explain why the
effects happen in the "chicken and egg" sense you you should not worry
about that.

Newton first, and later others like Einstein, presented models that
unified the two phenomena you mentioned, orbits and free fall.
Actually, a free fall is an trajectory that falls short of becoming an
orbit because there is not enough mechanical energy to keep it that
way.

If you give a high enough velocity to the rock in the right direction
and you lete it free, and thus is has the right Kinetic Energy to
balance the Potential Energy, it will go into a orbit around earth.
This is what satellites accomplish after gettign escape velocity.

I think you question is so elementary that shows you did not study
introductory physics in neither high school or college level.

No proble, as long as you agree to open a book and study. Any book
Physics 101 will do it.

Earth was created first by TOJ TAA-TO A = he.d.holy.she.it E.Art.|=|
is art of Capitol A. When time came to eliminate the evil from earth
The Holly six titan.titana, gad.goddess and devil.satana putted all
them evil guys on spaceshutle loaded with dedanoe's timed armageddon
bomb and they sent them in dip space nine. the bomb went ka-boom and
so bhsun was created. the bhsun doesn't fall on earth because it was
designed to be self-carried lika tao=yinUyang. ever since that bhsun
supports life on eart|=| in replacement of the diesel energy of the
dead. hope you're happy with this answer

If you throw it straight up it comes straight back down and hits
you on the head, so you'd better step out of the way.
If you throw it up and forwards, it still comes down but hits
someone else on the head. You don't need to step out of the way.
If you throw it really hard it goes a long way and hits someone
else on the head, but they are so far away over the horizon
you don't see it happen; but you need a big gun to do that.
If you throw it really, REALLY hard it goes way over the
horizon and falls, but the Earth curves beneath it and it misses
the head of the person on the other side of the Earth, carries on
around the Earth until it hits you on the head from behind, so
you'd better step out of the way. You have about 90 minutes
to move if you can throw it at 17,000 mph, which is really,
really hard to do - unless you have a really big, big rocket.
If you have a really, really, big, big rocket that can change
the flight path at the highest point it will still fall around
the curve of the Earth but never get any closer and you
need not move out of the way. Here is a picture of a
really, really, big, big rocket.

If your big rock had a tangential speed of over 18,000 miles an hour it
would not fall to earth.  Consiser all those satillites in low orbit.
They are big rocks thrown by rockets.

In -Pricipia- Newton drew a diagram showing how a cannon could launch a
cannon ball that would orbit the earth without falling back to the
ground. (of course he ignored air friction to make the point).

For Sanny, it was as though Isaac Newton had never lived.

Bob Kolker

ever lasting orbiting around earth is possible if you put one
sattelite on height D and fire it tangentially with force F where |D|=|
F|. what is no force later becomes distance and what is now distance
later becomes anti-force and so the task is solved. there is no such
thing as a first, second or so cosmic speed. newton is new with this
lecture

You assume the Earth isn't moving but it is. So one can also ask as
the Earth is moving very fast why doesn't it leave the sun behind?

Here is how it works,

1. The speed of the Earth means that the Earth will keep travling away
from the Sun.

2. The gravity of the sun means the Earth will be pulled into it.

The answer is as both A and B are right they split the difference and
the Earth does not move away from the sun or fall into it. It stays
the same distance away.

there is atlas you know,

and he takes care of al that,he has the whole earth on his shoulders,

did you know that??

I am not sure whether atlas does that ,or god, anyway somebody must be
doing it ,

otherwise we would fall ,would'nt we????

believe it or not,

all true!!!

there are/were also some people like einstein ,

who say that mass dictates space how to curve, and space in his turn
dictates mass how to move,but what kind of bullshit that is ,I don't
know,but that cannot be true can it???

This is a deep question. It goes right to the heart of why gravity
and space behave the way they do. As posted above, Newton and
Einstein have given us mathematical models of *how* gravity and space
behave but not *why*. The only answer that comes to mind is the
anthromorphic principle, which seems to me to be not quite satisfying.

When you throw a stone horizontally, why doesn't it fall straight down
(doesn't gravity pull it down)?
What if you threw the stone faster?  What would it do?
What if you could throw the stone much, much faster?

Didn't you learn this in high school?

What's that?
