Please can u explain me the whole unit on motion of grade 11 university:)

That's huge!! You'll have to post the questions where you have difficulties, then, we'll be able to help you. Or if you insist, you can study your book and say what and what you don't understand.

Take a crack at it, Unknown008! It'll keep you busy for at least half a year!

:D :D :eek: :eek: :D :D

LOL! I have my own things to learn, my own physics (on ideal gas, thermodynamics now), my chemistry (organic chemistry now, halogenoalkanes)
And my math (this is more practising, complex numbers).

Why would someone actually ask for another to post all there is to know about motion? :confused:

I do not get it. That is one mighty broad topic. There are books, googling, etc. This would be a lot of typing.

Hey, Unknown, how about posting everything there is to know about Electrohydrodynamics?:p

Every time I try to give you or Perito a rated answer, I get that infernal 'pass it around' business every time.:(

I wish the powers that be would put a stop to that, if they can.

I am just teasing. Few have studied this. Google it. This particular field is notorious for being

difficult and advanced. It is the study of electric fields and fluids. It involves the Navier-Stokes equations that must be solved simultaneously.

It takes a special brain to delve into it.

Have you ever heard of a 'salamander drive'? Remember that fancy Russian sub in the movie "Hunt for Red October"? It is propelled by seawater being funneled through and using an electric field and magnetism to drive the sub. It supposed to be silent.

That is the field of electrohydrodynamics. That sub drive is called an 'electrohydrodynamic drive'. It also relates to astrophysics. There is a section in

Wikipedia about it. It sounds like a fascinating field if one has the gray matter to understand

it. Google it if you want to read some fun stuff.;)

That indeed sounds interesting! I'll have a look some time. *bookmarks the thread*
