If you could travel to the middle of the Earth what effect would gravity have on you?

Would gravity be lesser, greater, or the same during your travel? If you were between the core and the surface would you be 1/2 your current weight lighter or no change? Or does the overall mass of Earth determine the effect of gravity?If you could travel to the middle of the Earth what effect would gravity have on you?When you're at the surface, all of the Earth is below you and pulls you down. At the center you're surrounded in all directions, the pull in all directions would be equal, and you would experience no net gravity.



As you descend from the surface to the center the gravity would gradually decrease. Only the part under you attracts you. E.g., when you're at the surface, you're on a sphere with a 4000 mile radius (rounded), and all of it attracts you. If you're 1000 miles down, the outer 1000 miles of the Earth has no net effect (it's pulling in all directions equally), and only the 3000 mile radius sphere under you is attracting you. As you get closer to the center, more of the Earth is above you and doesn't affect you until at the center, you feel no gravity.



You'd probably feel a great deal of heat and pressure, though. At least for a fraction of a second. :)



Add:

Rochester is correct about still feeling the Moon's gravitational attraction. It would exert a force of around 7 thousandths of one ounce. You'd also feel the gravity of the Sun (much larger - around an ounce), plus minor contributions from Jupiter, the other planets, and every other piece of matter in the universe. He's wrong about where you'd have to go to feel no net effect, though (e.g., the center of the earth-sun system is inside the Sun, but you can feel no net gravity from that system very near the center of the earth by moving a tiny bit toward the Sun).If you could travel to the middle of the Earth what effect would gravity have on you?
if you were in the center of the earth your body would probably collapse in on itself because of the entire weight of the earth coming at you from every side of your bodyIf you could travel to the middle of the Earth what effect would gravity have on you?lol the gravity will remain the same

the pressure will increase thoughIf you could travel to the middle of the Earth what effect would gravity have on you?
You would be squashed like a bug!If you could travel to the middle of the Earth what effect would gravity have on you?If we grant you the ability to withstand the heat and pressure there, you would find no net gravity from the earth, since there would be equal parts of the earth exerting gravity on you from all sides.



You would, however, feel the gravity of the moon. To find a place with no net gravity from either the earth or the moon, you would have to go to the center of gravity of the earth-moon system, which is located somewhere between the center of the earth and the point on the earth's surface directly below the moon.If you could travel to the middle of the Earth what effect would gravity have on you?
w = mg

w = person weight

m = person mass 100

g = gravity acceleration 9.8



on the surface of the earth

w = m * g

w = 100 * 9.8 = 980



at the center of the earth

g = (G)(M)/(R ^ 2)

G = gravitational constant 6.67E - 11

M = mass of earth = 5.98E + 24 kg

R = radius of earth 6.37E + 6 meters

if R = 0

g = infinity

w = infinity (theoretical squashed)



if half-way to center of earth ( R = 0.5)

g = constant / (0.5 ^ 2)

g = constant / 0.25

w = 1 / 4 of normal weight
