Earth's Rotation Speed: Would We Notice?

If the Earth for some reason started rotating faster would we notice it? Would we experience any g forces?

We would certainly notice it! The day would get shorter.

And your satelite TV wouldn't work.

I think he means would we feel it.

Depends how much it speeds up.
At the current length of day, somebody at the equator weighs about 0.25% less because of the Earth's spin - so you would have to be a particularly finicky anorexic to notice.

My bad, yes I meant would we feel it.
