Why does gravity and acceleration feel and act the same?

ok, but why is our hair not blown backwards with such speed. How much faster would the world need to speed up to do this, or doesnt it matter.

Which speed, the speed of the Earth revolving on it's access, or the speed at which it is orbiting the sun.

Chip Monk missed a bit. If the Earth stopped spinning then your motion would be at a tangent to that rotation (not as some people thing, up into the air). Given that you are so small compared to the curvature of the earth you would really just go along the ground. That would be predictable and constant, you would always go in the same direction, at a tangent to the the spin.

If however the earth stopped moving along it's orbit around the sun, then you would move in a tangent to that orbit. So It would depend where you were relative to the orbit. If you were effectively at the back of the Earth, relative to the orbit then you would hit the Earth when it stopped and you didn't. If you were at the front then you would spiral into space, you would leave the earth because it had stopped, but you would still have the spin. You wouldn't spiral relative to the Earth, as it was still spinning but you would relative to other things.

If both motions stopped it would get really crazy.

....as opposed to just one of the motions.

Just stick your head out the window.

We'd all be vivisected.

Yes, I thought that was perfectly clear,

I Found A Website That Will Explain Perpetually Expanding Matter As The Cause Of Gravity In More Detail:

http://mikeschuler.web.aplus.net/index.html

Particularly The "Light Does Not Bend" And The "Acceleration Is Gravity" Pages.

Have Fun! This Is Not Easy Physics!

Why would you put a capital at the start of every word.

An also I hope you meant the "Particularly The "Light Does Not Bend"" pun.

Aristotal, lol.

Happened to me too, this time in the cellar. I was also busy..trying out that tinfoil hat.. that I had just recovered from my new energy/matter transport device (time machine)... when there was a knock at the door...
