It does, continuously. It keeps missing.

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?

Oops, I meant to write ? faster ?, not ? higher ?:
? If the earth's orbit around the sun happened to be slightly faster

it'd be Spiraling Away From the sun ( a bit more each year );
conversely, it'd be spiraling Into the sun. ?

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.

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???

[snip]

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.

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.

Whoops! The force (gravity) is directed toward the sun and hence
the
acceleration is directed toward the sun.

Whoops yourself. If the acceleration was all toward the Sun, the
planet
would fall into the Sun, just as the OP perceives.

The Earth does fall towards the center of the sun - continuously.
It has been falling towards the center of the sun for 4.5 billion
years now.
It never gets any closer because of its tangential velocity - earths
momentum wants to move the earth in a straight line - the acceleration
of gravity pulls it off course constantly and makes the earth move in
a circle (an ellipse really but lets keep it simple).
If gods hand reached down and stopped the earths motion - and then let
go the earth would slowly move towards the center of the sun getting
faster and faster - if gods hand reached down and gave the earth a
sideways push - it would fall into orbit.
The orbit is the place where the tangential motion is exactly balanced
by the inward acceleration.

It is the right angel acceleration that keeps the planet from falling
into
the Sun.

Not acceleration - constant speed - momentum.

It has to be acceleration, otherwise there is no ballance for the
accelerating force of gravity from the Sun.

The suns gravity pulls the earth towards it - what pulls the earth
"sideways"?

There is no such force - there is momentum and there is the force of
gravity.
Together they guarantee that the planets orbit in an ellipse.

Satelites orbit the earth without having to constantly fire their
rockets.
If they do fire their rockets to increase their tangential velocity
they go into a higher orbit.

If something pushed the earth sideways it would move into a higher
orbit.
If something retarded its sideways motion it would fall to a lower
orbit.
If there is Zero sideways acceleration - it will orbit at the same
distance from the Sun forever.

Any change in velocity is an acceleration - if you draw the vectors
the *change* in velocity is directed towards the center of the circle.
the *change* in velocity in the tangential direction is zero, none.

If God's hand really were in this--and it could be--and he mysteriously
somehow made the Sun wink out of existence, The Earth would continue in
the
same line it was in at the disappearance, but would continue to
accelerate...and accelerate...and accelerate...until it reached the
fastests
of all possible velocities.


No - to accelerate it needs a force - there is no tangential force -
if the sun winked out of existence the earth would continue on at a
constant velocity.

Please don't argue with this - I am not trying to fool you - I am not
lying.
I am trying to teach you something - for free!
(I do have a degree in physics by the way - normally I would charge
for tuition)

You just need to think carefully about the fact that acceleration
needs a force - staying at a constant velocity is just momentum.

I think you can do this Mark - i have faith ! - just think about that
rock on a string whirling about your head - the only two things going
on are a central force (acceleration inwards) and momentum.
