How is proper acceleration defined?

Main Question or Discussion Point

If we are accelerating in a uniform grav field, we are unable to feel it.

In that case, are we still considered as undergoing proper acceleration? Will we follow a hyperbolic path?

Hi OMFG Clown
No, in this case acceleration is defined by forces acting on the body. Measurable by an accelerometer. Free falling in a g field would have a null reading ,,no force.
There is still coordinate acceleration as measured by external frames. As charted in at least some of those frames it would be a hyperbolic path.
So your motion would be inertial , not accelerated.

I can't get my head around that just because we can't measure it, we consider it inertial.

Funny that you're replying to a banned clown.

I have a funny feeling that I'm gonna be banned pretty soon too.
