Im having a hard time understanding why we feel acceleration. If a rogue planet crossed our solar sistem close enough to pull us away from the sun, accelerating us until we are expeled into the cosmos, would we feel this acceleration from the surface of the earth?
In: Physics
You do not feel acceleration due to gravity, no, because it is exerting force on every part of you equally, so there is no internal force in your body that you could detect. This is why astronauts in orbit are “weightless.” In reality they are almost as heavy as they are on the ground, and are accelerating at 8.7 m/s^2 at all times. But as far as they can “feel” it is indistinguishable from there being no gravity at all.
