thanks, sorry for that stupid ques about mag field changing with position... i don't know why i asked that?

So for the case you considered my friend is right? And will it not be the same if the field was changing with position.

We had this ques. in a test - "can a changing magnetic field change the speed of a charged particle". The ans given to us was "no because it's velocity is perpendicular to the magnetic force due to the mag field" but a friend of mine wrote that a changing mag. field will induce an emf which...

I was under the impression that i understood your answer but then later i thought about how when a disc is rolling 'purely' we can consider it to be rotating about an instantaneous axis passing through the pt. in contact with the ground as well as a moving instantaneous axis through the centre...

I think you misunderstood the question or i am unable to understand the reply... What i asked was that in the fig. If body b is rotating about axis aa' then can we say that there can be an axis mm' parallel to aa' about which the body's motion can be described as rotation? Can that happen with...

Does a body rotating about an axis also rotate about any other axis? Eg. Cars on a racetrack may be rotating about a vertical axis passing through the centre of the track but can they also be considered to be rotating about a vertical axis passing through the spectators' stand?

Okay, so we say dynamics doesn't occur in real space because all the different states can't be determined for which we'll also need velocities and in that sense physics of stationary objects or statics can occur in real space... Also saying dynamics doesn't occur in real space and saying that...

okay, now i understand it somewhat...but can you also please tell me what the proffesor in the video means whenhe says "dynamics is not happening in real space but in phase space which is both velocity and co-ordinates" at 19:45 http://www.youtube.com/watch?v=8X1x9RLaaxc&list=PL3E3224DA58C14109

Yes, i did but i could not get a feel of it...i mean I'm not able to put it in perspective with real world the way I'm able to do with 3 co-ord. system... I also tried looking at the "space" page of wikipedia but could not understand it either... Tnx

What exactly is phase space and how is it different from real space i.e. 3 co-ordinate system? what does it mean when someone says "dynamics occurs in phase space"? I'm very new to all this so pls take that into account to
