33Try HCV
By the way its just u add ur(observer) velocity's negative to the body being observed
Can any one explain me relative motion? I tried studying it from comprehensive but I could not follow.
Please help......

1Read HCV's small and innocent theory with deep, devoted, disciplined concentration!!!!
Try out the solved examples too given there.... if u want 2 do swimmer-man/Rain- man problems, then try out ur book(COMPREHENSIVE OR ABC) BUT 1ST GET THE BASIC RIGHT FROM HCV!!
1they have told you right....... if your basics are good you can solve any problem.............. whch chapter i faced a little bit problem i first read the basics just one time and notes important concept....... then you just think about it with full concentration........ the day after you can see the problem frm ncert or hc verma............. try to do it yourself..... but you face first a little bit of problem........................... then you can see the solve example and try to do that exs another day............................ after you have a little bit of idea about the chapter then read it again... you can grab it very quickly..............................
thanks.................
1I read the frames of reference part given in HCV. There you have this equation :
vp,s = vp,s' + vs',s
How do we know which is the velocity of the particle and which is the velocity of the non inertial frame in problems like rain-man or river-man. Is it like the subject of the question becomes the particle and the other one the non inertial frame ?
1@pranay... vp,s implies velocity of 'p' wrt 's'
i think u will be more clear about the concept after solving a few problems...
11st, get d concept of vectors clear.
Then go thru the diagram of rel.vel. given in hcv( alongwiith d theory).
if u have d concept of resultant vectors( by triangle method or any othr meth) clear, den its quite easy!![1][4]
23va/b =va - vb = velocity of a wrt b = velocity of b as seen by a
yo, for dis u most knw the basics of vectors.
1the velocity of a body B wrt body A is simply the velocity with which body B will be moving as observed by an observer on body A.
for that we bring A to rest by applying a vector -vA on it and also do the same on B wich gives the relative velocity of B wrt A vBA=vB-vA.
1@ Euclid - The velocities which I was talking about were both with respect to the inertial frame (say ground or river bank). So say in rain-man problems if we are given the velocity of rain with respect to ground and of man with respect to ground then which is which according to the above relation ?
6well u need to hav a sound knowledge of vectors bfore u can understand this topic....
1arey use the same eqn yaar...vrain,man = vrain,ground - vman,ground
note:- all above quantities are in vectorial notation
