Thank you for adding this. I feel vindicated somewhat. The other posters addressed other interesting issues but not really my question directly so I kind of gave up figuring I was out of my league.

That's where I get confused. Gravitational and coordinate acceleration. Or is it proper and coordinate acceleration? Or proper and gravitational acceleration? I guess I understand proper acceleration.

The math is not a problem. I Can do the math.

I'm working on it.

Coordinate acceleration. Yes I think that is where I'm running into problems. I'm thinking in terms of actual acceleration as opposed to theoretical acceleration.

So acceleration of gravity is a phenomenon that no one really understands and can only be explained by mathematical representation?

Acceleration as I understand it is constantly changing velocity. Velocity is distance over time.

I just started Engineering school this year.

I don't get any of it. I don't know enough about all of this to understand a graph like that.

Ok so does that mean that the acceleration of gravity is basically just an illusion? Or a quirk of geometry?

The guy in the video lost me when he retuned the graph back to zero gravity and then proceeded with his explanation as though there was still gravity. How could that be if the graph was returned to zero gravity? So this is how I understand it. Let us imagine a little moon sitting out in space...

I think I've heard that called the law of equivalents?

Yes I understand that light speed is always constant in a vacuum, slows down in a medium, but I'm afraid I don't get that video.

Why do objects accelerate when falling as opposed to a constant velocity?

Thank you!
