it would accelerate until it hit the center of the earth and then start to slow on as it passed the center until its velocity would be zero at teh othe rside. then it would fall back down and repeat. (ignoring friction and any coriolis force)

And as you go significantly deeper into the earth, the strength of gravity will weaken as well. Salviati Oct 2023 #26

thats roughly the answer i calculated moonshinegnomie Oct 2023 #3

I'm surprised that prompted heated debate caraher Oct 2023 #22

If you substitute air, with water, it becomes easier to imagine. The water pressure at the bottom Chainfire Oct 2023 #6

How about this? usonian Oct 2023 #7

if you dropped a ball thru the earth it would oscillate from one side to the other moonshinegnomie Oct 2023 #9

That is what I assumed as a 12 year old. That it would bounce back and forth until it slowed to a stop in Chainfire Oct 2023 #15

air is compressable moonshinegnomie Oct 2023 #10

Of course, but at the pressures that exist under the eggshell thin crust Warpy Oct 2023 #11

i dont know if it would be liquid or solid or gas moonshinegnomie Oct 2023 #12

Air, would certainly be a gas in a zero gravity system, unless it was super cold, I don't believe the proposition Chainfire Oct 2023 #14

PSI is a measure of weight. Chainfire Oct 2023 #13

no it isnt moonshinegnomie Oct 2023 #16

It certainly is. Pounds per square inch, as referring to a column of water, for instance Chainfire Oct 2023 #17

Yes, and weight is the relevant issue, I think William Seger Oct 2023 #18

No, it isn't. sl8 Oct 2023 #19

Yes, but in this case, the pressure is due to the weight William Seger Oct 2023 #20

This would be a nice homework problem for an upper-level college course caraher Oct 2023 #21

This is the best answer in the set. Some comments... NNadir Oct 2023 #24
