Well...I think your play on words is a little confusing to most people that read the basic question you asked. Gravity is not
a moving force, i.e., it does not come and go, nor does it move from right to left or vice versa. It is a relatively constant attraction inward - downward toward the center of mass (assuming you are on top of the Earth).
Take any good magnet and place it on a wooden table top. With another magnet, feel the force of attraction or repulsion that you get as you move the free magnet around the one on the table top. It is pretty much there all the time, not moving. Right? Same
with gravity, only we are dealing with a huge magnet, the iron core of the Earth. Trust me, the core of the Earth does not move around a lot. It may shift some (the North Pole does wander around a bit), but it does not get up and move 500 or 1000 miles per day.
If it did we would certainly feel it.
Keep in mind that the core of the Earth is a huge molten mass of many different types of metals. Visualize all that molten stuff sloshing around under the crust of the Earth, and squeezed by tons upon tons upon tons of rock and sand and other stuff above it. If it squishes a little more over here than over there, maybe you get an itsy bitsy change in location of the North Pole/South Pole.
But, that change is not drastic enough to be called moving, and certainly not fast enough to be detected by man on the surface.

The motion of the Earth relative to the Sun is in continual acceleration .The Acceration of the Earth is variable proportioanlly as the Inverse square distance of the Radius vector that sweep the eliptical orbital of the Earth. The Astronauts when climbing into space Experience changing acceleration. Now the Question is ,if they have butter flies in their stomachs as the accelerate into space from the Earth,Why dont we also feel the effect of acceleration as the Earth revolves around the Sun?We are subject both to the acceleration toward the Sun and also we are accelerating on top of the surface of the earth toward its center at the Rate of 32 feet per seconds each second of time. It appears that that question was answered in Einstein's First Postulate of Special Relativity Theory. If the Postulate is correct than that would be the Answer to your question.

gravity has nothing to do with magnets. Lets say you are in a car that is just about to make a left hand turn. Just when it turns, you are accelerated towards the direction of the turn and your head tilts in the direction the force is coming from. Just like if you sat in a chair and I push it from behind, your head snaps back, toward the direction of the force. Now, if the car continues to turn, say in a big parking lot, making a slow circle, eventually your head and body will become acclimated to the turn, you get used to it and you will be able to function as if nothing is happening. Same with the earth - we are acclimated to the acceleration.
If you went to the planet Jupiter, you wouldn't be used to it - you would weigh thousands of pounds, you'll feel the acceleration because you won't be able to move - you'll be on your back - Just like if you were launched from a rocket at an extreme high acceleration. You'd be on the floor of the rocketship - unable to move.

The force of gravity is indeed a moving force for us, since we're moving along the surface of Earth as it rotates. This acceleration does exist, and it's responsible for the force that produces the Foucault's Pendulum's rotating movement and the direction of sea and air currents on both hemispheres. This phenomenon is known as Coriolis' Force, and we don't feel it because its magnitude is very small compared with other forces that act on us everyday.

You don't feel "acceleration" because you aren't acceelerating. You do feel the force of gravity--as weight.
If you are accelerated by another object (as in a car that is speeding up, you feel acceleration in the way you are "pushed back" into the seat.
And, if you step off a cliff (please don't test this, just take my word for it!) you will feel a sensation of falling. That's not "feeling" acceleration exactly--it's your body's response to not having itself pulled against the ground the way its supposed.

We are being constantly accelerated outward from the center of the gravity well, relative to the gravitational framework.

You feel it every time you fall down!

Hi. We do. If you didn't feel it you would be in free fall.

You do. That's how we stay on the ground.

You do .. it's called your weight.
