actually what effects is the force dat is acting on d man.Now as u know dat mass is nt a force but weight is a forceso obviously weight acts dere not mass.U cn understand it by dis dat if a man falls on a body in a gravity free space den nothin vl happen, no matter however is d mass of man, as deres no gravitational acc dere and dus force acting is zero.Note: Plz note widout gravity falling is nt possible , i hv jst taken dis assumpion to clear ur doubt.If u get ryt answer den read my article in community shelf.Its wrth reading.

pseudo forces r actually nothing but an adjustment dat we do in a non-inertial frame of reference , so dat we can apply newtons law to it.As u knw dat newtons laws r only applicable in inertial frame of referencesSo to apply newtons law in non-inertial frame we apply a fictitious force on d body, whose magnitude is equal to (mass of body* acc wid vich d frame of ref is moving)and dirc is opp to dirc of acc of ref frame.hope it clears ur doubtif yes den read ma article in community shelf, its wrth reading.

actually when a body is in circular motion , then it requires a centripetal force (acting towards it center) .If motion is uniform circular motion den d force remains same always(in dis case tengitial vel of particle is always same).But in non- uniform circular motion , the tangential vel keep on changing and dus d force reqd to keep d body in circular motion also shud change respectively And dus d centripetal acc , shud also change.Mathemetically , a(centripetal) = instantaneous rate of chng of tangential velocity.hope u get d ansif yes , den read my article in community shelf.

COM is actually a pt where a particle can get balanced . So it is nt d center of a body or nething elseIt depends on hw d mass is distributed in dat body.It can at geometrical center of body or evn outside d body or at corner.hope u get ur answer

hey buddy
first of all yaar dont panic at all.
Dis pressure & dis panicness vl not let u clear JEE
But if u lv it ,den i am sure dat u can still clear JEE.
first of all yaar JEE is not dat tough as made by all dese coaching banners .Jst it requires a conceptual approah.So for it u hav to be conceptually strong.Coz in JEE dey always tests ur knowledge nothing else.So JEE doesn't means doing or solving thousands of ques but it is about doin the gud ques only in which u need to appy ur brain jst formula knowing is nt enuf.
But i think u shud do dese topics first:
Phy: Mechanics,Optics,Electostatics & Magnetism
Chem:Organic ,bondind
Maths:Calculus,Complex no,vector & 3-d
atleast yaar i think u shud do dese topics thoroughly,
& do take more advices frm ur teachers
ok
Abt buks i cant suggest many but acc to me dey t enuf if done sriously:
Physics: H C Verma
Chem: RC Mukerjee,Arihant
Maths:S K Goyal & M L Khanna
hope its useful

hey buddy
best way for JEE preparation is to make ur concepts strong.Coz in JEE dey always tests ur knowledge nothing else.So JEE doesn't means doing or solving thousands of ques but it is about doin the gud ques only in which u need to appy ur brain jst formula knowing is nt enuf.
So do a gud study ,dats all.
And dont think dat JEE is tough ,its not lyk dat at all.But all dese coaching centers hav make a gr8 terror of it in students & most students can't handle dis presseure only & dats why dey fail.
And in my prep days one bro told me dat"" u vl clear or jee or not but the hardwork u do for JEE & all dese preparation vl always remain unforgettable to u & vl always help u in future""
So jst be cool & composed & make ur concepts strong .
Abt buks i cant suggest many but acc to me dey t enuf if done sriously:
Physics: H C Verma
Chem: RC Mukerjee,Arihant
Maths:S K Goyal & M L Khanna
hope its helpful

a gr8 gr8 gr8 article..very gud keep it up
each n every word u wrote above is true.
gud work

its is a very gud article
It's obviuos dat all of dese 99 points r not applicable on a single guy.
But most of dem r true just for evry1 & for other poits it depends on his personality
but still its a very gud article

hey gal u rocked
a very excellent article
hats off to u
It's tough just lyk u
a gr8 one

Hey yaar the replies given to u r very gud
means yaar the more persons u consult ,more u get confused
So acc to me follow Bhupesh sirs reply religiously & u will definitely get the fruit of dis hardwork
Best of luck to u
U can also read my article on drop
coz i think u shud know dese things before hand.
ok.
search it in community shelf,it may be on 3rd or 4th page
ok

hey buddy
wat u wrote is gud & as i 'm an old member of goiit i can say dat dis topic has been touched here,not only touched but has been fighted & argued badly here ,many a times
But yaar dere's no use of it
Simply no use
Actually u urself has written dat even aftre seeing movies like RDB & Chak De & all dat we ppl didn't change.Den did u think ur dis article can awale such persons.Dere's ony 1 way of awaking dese sleeping persons!!!!!! And dats our actions.U hav such idea in ur mind.I do hav it. And dere r many here presently & before also who hav d same feelings.If only we all didn't say anything & do something watever we can do at our own level .Either we may be indidvidual at dat tym , but still wen so may persons do it individually den also a mass action can occur.So luk forward it instead of trying to wake dese sleeoing selfish so called persons,jo padhna to IIT se chahate hain but job US mein chahate hain.
So buddy presently concentrate on ur studies & let ur action speak not u
best of luck for dis aim.

Hi frnds Dis is Prakhar again
Actually i also was not so gud or interested in Physics in my first year,especially mechanics was most difficult part dat seem to me ,but now after drop i must say dat Physics is d best subject & mechanics is its best part if one study in a proper way.For this actually i must thank my teacher Mr.P k Siddhartha who makes me know the real physics & dats why its my strongest subject now.
Most of u use a common method,go to lectures ,try to grab the concept & then do as much ques as u can of HC Verma or other buks .Also u will do ques of work-energy with its formula only & rotation with its theorem.But in this way my frnd u r actually not learning physics u r just learning ways of solving a particular ques.But wen u will sit in JEE may be ques can be done only frm simple mechanics(means using 2nd law only)in an easier & time efficient way.For developing this thing u hav to change ur approach.U shud hav d feel of subject.U shud know dat its not oding the no of ques dat matters the only thing matters is in wat way & how many ways u can solve a ques.
So i advice u if ur doing any ques then try the ques with any other way also .Ask ur teacher to tell u any other method of solving dat ques.May be its ling but at least if ur able to know it den u can use both methods at one time & do any ques in shortest possible.Also by this u will urself able to find the right method doin any ques.For example if u do a pulley ques & its a fixed wedge ques.Then solve it with mechanics also & den try to do it with work-energy principle also.Then think wat will be the case if wedge is also not fixed..In this way may be u hav done only 1 ques in 15 minutes but u hav get the concept in ur mind for rest 5 ques.
And for thid do just H C Verma.It has got many ques & if u try the ques in this way frm dat buk den u will find wat quality of ques they r giving i dis buk.If u complete dis buk in my told method den mind we u will never face any problem with physics atleast in JEE or any other engineering exam.
DROPPERS BEWARE:Use this method if u feel u hav enuf time & u r not neglecting ur maths or physics.Coz wen u start doin dis thing u got more interest in physics & ur other 2 subjects start suffering.
So Hope it helps
Cheers
