when am I supposed to use Lorentz velocity transformation?

i don't even know what that is. something to do with relative velocities? (in which case, it's always active?)

Well, thats sort of the question, mate. Although I think its always active, too.

I wish my physics notes were neater... we learned this.

You should only apply anything when it's going to have an effect on the outcome -- if someone's running on the ground and you're standing next to them (so you're 'stationary'), then don't bother. If you're in a car and they're running alongside, you would.

So basically, whenever the observer's and oberservee's (um?) frame of reference has a difference in absolute velocities

another toxicbug "do my homework" thread

read a textbook, homo. you might learn something

or just google it ffs

i dont think the idiot knows how to google. and reading is not an option.

Yea, you use it when dealing with relativisitic velocities.
Different frames of reference and all that.

Is that 1 / sqrt( c^2 - (v^2/c^2)) ???
I forget.
That's the part everyone leaves out in E = mc^2. It should be E = gamma * m * c^2, where gamma is that formula I posted.

Its 1 / sqrt( 1 - (v^2/c^2)) actually.

Goddamnit, stop doing this retard's homework for him.

duh

i think whenever is fine
