## ShikhaDessai 2 years ago where is acceleration due to gravity the most?

1. sesidhar

i think at the center of gravity

2. mayankdevnani

the acceleration due to gravity there will be REALLY high since mass is nearly infininte and the size is so small. so theoritically if u survive to even come cloe to a black hole u will have an acceleration gradient actin on u which will rip u apart. but on the earth the gravity is more on the poles due 2 factors:- 1) the effect due to the angular rotation of earth is miniumum or zero at poles 2) the earth is flatish towards the poles so g is more at poles. The acceleration due to gravity is maximum at the poles.

3. mayankdevnani

is there any assumptions that we should take note of before analysing this question?

i didnt quite understand the complicated words

@mayankdevnani

for example, taking the case of a full, solid planet, and hollow planets, and black holes etc each have different cases.

in the earth system , acceleration due to gravity is strongest in magnitude at sea level ,

UnkleRhaukus is right: attraction will be greatest at the attracting body's surface.

@mayankdevnani is correct

17. mayankdevnani

thnx... @soty2013

mayak is a little more right if we limit our discussion to the earth, and Uncle is right if we don't limit it.

Nope, sry - the gravitational pull is _not_ the biggest on the surface. At the transition from mantle to outer-core, the pull would be strongest, I think. (maybe I didnt consider some other case, but it sure is bigger than on the surface). Then again, if you limit yourself to "no-digging-holes-allowed" , you probably want to hear something like "at one of the geographical poles". This is of course, cause centrifugal force due to rotation would negate gravity to some point everywhere else. (note, that I didn't take into account the earths geoid-shape. But I guess, that'd be overkill in our case)

on the surface of the earth...

22. MuH4hA

As opposed to what? 100 kilometers above it? No pellet sherlock ....

i simply cannot understand the high terms that all of u r talking about

24. MuH4hA

The problem is, that your question is rather vague.. When asking questions, you have to be specific about what you want to know. Also, if you do not understand somethig, how about "I don't understand XY, could you please elaborate what it means?" or something like that... Just saying that you don't understand doesn't help - u gotta tell us _what_ you don't understand and _what_ you want to know.. ok? :)

see first of all, i got totally different answers....

26. MuH4hA

Again, that's because your question was so vague - different people interpreted it differently... now _what_exactly_ do you want to know?

no thing is i came to know that acc. due to gravity is max at the poles, but i did not understand what Vincent-Lyon.Fr said. He said that UnkleRhaukus is right: attraction will be greatest at the attracting body's surface. i did not understand THIS

28. MuH4hA

Well, they for example assumed that you don't want to take into account, that earths density is not the same everywhere. They assumed, that earth is a perfect sphere and the density of the material is the samer everywhere in this sphere. If one takes that point of view, then yes - gravity will be strongest on the surface of that sphere. It will decrease if you dig a hole and move towards the center and it will - of course - also decrease as you move away (as in: above) from the surface. Whether you wanted to make this simplification or not, we don't know.. you didn't specify..

ok ok i got it........thanks

30. MuH4hA

note that I for one, didn't think you wanted this simplification and told them, they are wrong. Just 'cause I thought that it would be too trivial.. but well.. maybe you did want it.. idk :P you're welcome

meaning? u told them they were wrong?

32. MuH4hA

meaning: we still don't know how the original question was to be understood. But nevermind - as long as you got the answer you were looking for, it's all good ;)

33. UnkleRhaukus

we are attracted to the earth because it is a Big ball of mass, the closer we are to the mass the greater the attractive force, , if we were falling down a crack in the earth ; as soon as we go below the surface , some of the mass of the earth is above us , so the attraction is no longer entirely downwards. as we reach the center the half of the mass is above us and we are attracted to both sides evenly ,

ohk....anyway i'm sorry if u didn't understand my question, but according to me it was quite clear...u might have advanced in this topic so maybe u had many things in mind @MuH4hA....i don't know....anyway i'm gonna close it:P

ohk @UnkleRhaukus
