Hey all, here is one for you..... Is it possible for the earth to spin faster at one point then another? Example, Lets say you put an object( not moving) at the equator and you put another object somewhere around the north pole. We put the objects on the same latitude line so they are exactly stright up and down. will the object at the equator spin faster then the object at the north pole due to the curveture of the earth??? I have a bet on this I say no way. What do you all think?

If you put the objects on the same latitude line they would either both be on the equator or both at the north pole. But anyway your question depends on if you are talking about speed in terms of RPM or distance traveled. Everything is spinning at the same RPM, but the farther you are from the axis (the polls) the faster you have to travel to make the same RPM.

The one at the equator will travel more distance. Just like the outside groove of a record is longer than the inside groove. (Hope I am not showing my age by referencing vinyl record albums.)

Are you talking about the Coriolis effect?

then I believe the answer is the closer you get the equator the lower the Coriolis force is and actually is 0 at the equator, The force is clockwise above the equator and counterclockwise below the equator.

I thought it was one long groove! Groovy man! sorry, sorry...

unrelated question....

How does the water move when you flush a toilet located on the equator? Since it rotates as it drains CW north, and CCW south... would it just "dump" if on the equator?

I knew someone was gonna bring that up as soon as I posted it.

Will they both show up at the same time. (A 24 hour period) I mean the rpm is the same 24 hours in a day there is no debating that what was said is that the one at the equator would have to move faster then the one at the pole. Is that a true statement?

Ok lets try it from this view. the earth is one mass, not seperated, If it takes 24 hours to go around 1 time how is it traveling at any greater speed anywhere on it. I guess thats what i don't understand. I'm not a physics guy but this has sparked my interest. I don't understand alot about science but will someone please explain to me how this is possible. If im understanding it then it should take more then 24 hours at the furthest point away from the axis, but it doesn't it still takes 24 hours no matter where you are on the earth right???? Please explain

"If im understanding it then it should take more then 24 hours at the furthest point away from the axis, but it doesn't it still takes 24 hours no matter where you are on the earth "

key word "furthest"
this implies distance.... same time, different distances........speed of equator (further) is greater .

Sorry, call me stupid or whatever, but it still gets there in a 24 hour period. explain that.

think about this again.....measure the circumference of the record, CD, or what have you...now measure the center hole's circumference....
right... the outer circumference is greater.. lets say it is 10X greater than the inner.....that means it has to travel ten times the speed of the inner to get to the same point of each revolution.

it makes since to me when i do the math. i guess time and distance being 2 different things is what has me. Anyway you have been helpful i guess im going to have to suck it up and pay my bet.
thanks

you could still win the bet, if the question is as stated above..all depends how you agree to interpret "spin" as being "rpms" or "distance per time"...
the RPMS of the inner or outer are the same......just the distance traveled are different.
