Why is it that when something pushes/pulls on me, I feel acceleration, but I don’t feel acceleration from the earth’s gravity? I feel a force pushing upward on me, but I don’t feel a downward force.
In: Physics
You do not feel acceleration. You do not therefore feel gravity.
We sense “jerk”, the change in acceleration. When someone pushes you, you notice the push that suddenly causes you to accelerate; it starts quickly and ends abruptly.
We also sense change in velocities, which is commonly associated with acceleration. For example, when skydiving, I sense the air going past me faster and faster. I therefore know I am accelerating, but I don’t feel it.
I also can feel force. you push and pull my skin or bones, and I sense it.
