Answer 1

why is the acceleration due to gravity is less "dwn" the "mine" compare to surfce of the earth

dwn u mean down?
and mine?

Answer 2

yes

Answer 3

and mine is mine, is that what you wrote?

Answer 4

why is the acceleration due to gravity is less down the mine compare to surfce of the earth?

Answer 5

the force of gravity lessens as the object falls down the mine, the more you get closes to earht's center the more the weight and gravitational force decreases

Answer 6

the more you get closes to earht's center the more the weight and gravitational force decreases
y is that ?

Answer 7

earth's *

Answer 8

gravitational force is 1/a^2
i think i was wrong, the more you go deeper it increases

Answer 9

so the mass ad gravitataional acceleration increases?

Answer 10

earth's mass is under us as we know and the more you get closer to it the more it pulls you down

Answer 11

the acceleration due to gravity surprisingly decreases as we go up and as we go down. it's the highest on the surface of earth.

Answer 12

\[F _{g} = GMm/r^2\]

As you go deeper, r decreases, and M also decreases, but the change in M is negligible for a mining tunnel, but as you go significantly deeper the gravitational force will start to decrease at some point until you reach the center of the earth where M = 0 so Fg = 0

Answer 13

yes, that formula! i forgot it ;-;
