Gravity isn't distinct from acceleration though - how would it?
- paulsutter 3y agoThats why I asked. And they are different. If you throw a baseball in an accelerating enormous elevator in a vacuum, the baseball will follow a parabolic arc. If you throw a baseball on the vacuum surface of a planet, it will almost (but not quite) follow a parabolic arc. The force of gravity is lower at the peak, unlike in the elevator where acceleration is constant everywhere in the elevator. Therefore, you can distinguish gravity from acceleration
