Gravity force a pull?how come I dont feel a pull?

Answer 1

Okay so this will pretty much be an explanation from a classical physics type of view so we can talk about gravity as a force.

You're totally right.. gravitational acceleration is a bit of a different experience than another kind might be such as acceleration from a surface pushing on your feet or a rope pulling you through your hands. If you were in space falling freely towards a body (planet.. whatever you want.. anything with mass) because of gravity you wouldn't feel any acceleration at all.. even a fancy accelerometer would feel nothing.

The simple answer is that if you are accelerated by being pulled on by a rope you're holding (instead of gravity.. so you're at some place in space with so little gravity you can forget it for this experiment) you will feel it because the pull of the rope is transferred through your body as a strain between all your molecules. They're all hanging on to each other and getting pulled along by each other and your nerves can feel this strain.

If it's a push then it's pretty similar... you're in space, some place with negligible gravity, in an elevator with a rope pulling it in what you could call the "upwards" direction.. ie your head is pointing in the direction of acceleration.. and you're inside it with the floor of it pushing on your feet.. you can FEEL it! why? because the force starts at your feet and is transferred through all the tissues in your body compressing you and your nerves.. and you feel it.

You don't feel the gravitational acceleration because it accelerates every single atom in your body exactly the same way. They all speed up just the same way as each other and there is no force needed between them.

Think about it like this... if you were in the space elevator again and you were actually made of just a bunch of tiny pieces of stuff all unattached to each other... lake say you were made of sand or something all just floating there undisturbed at first... then the elevator started accelerating! what would happen? well you would end up all mushed against the elevator floor in a big pile.. why? because you had no internal structure to keep you stuck together... if you do have this internal structure with your bones and flesh all stuck together, like you do, then they would all be fighting to cling together and not squish together or tear apart and avoid mushing up on the bottom floor. You're a solid structure. Those stresses in your tissues are what you feel.. it's the attachment between all your little pieces being pushed on or pulled on in every little bit of you that you can feel.

Hope this helps!

You do feel a pull. As long as you're on the earth, you feel the pull of gravity, you just don't realize it. Only when the earth's pull is changed, do you start to pay attention. On a rollercoaster, when you start your initial descent, if feels like your stomach is rising in your chest. That is the sensation when the pull of earth's gravity is lessened, because you're accelerating toward the earth. Conversly, when you get on an elevator and go up, you can sense a "pull" toward the ground. That's the combination of gravity and the acceleration in the opposite direction. Basically, the pull of gravity has always been present on you. You've gotten used to it and simply don't notice it anymore.

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.

Answer 4

You do feel it. Raise your arms and see how long before they get tired from being pulled earthwards.

Stand a long time and your feet hurt from the pressure on the floor as your body mass is pulled down.

Climb on a chair and jump to the ground. The pain in your feet on landing is from gravity.

Answer 5

Jump off the top of a ladder, and try to stay up in the air by flapping your arms. You'll feel the pull of gravity, trust me!

Answer 6

Because usually you push against it with your legs. Try hanging from a branch for feeling the pull...

Answer 7

Jump up in the air, do you float away? No you are pulled back to the ground.

Answer 8

Because all these years you have not experienced the opposite,that is, levitation. If you ever have an opportunity to travel in a spacecraft, you might not ask this question.

Answer 9

Because it's a force that you have adjusted to. It's a constant force that you have dealt with ever since your fathers's sperm cell entered your mother's ova.

Answer 10

If you can't feel that than you should be levitating in air.
its only because of gravity you are standing on ground....
