Hello
I have a question about the meaning of this term "translating frame". Let's consider x-y axis fixed in one place. Now we can construct a unit circle with origin at (0,0). Now I am going to construct another frame of reference with origin at (1,0) (in x-y system). I will let [itex]\mathbf{x}^{\prime}[/itex] axis be parallel to [itex]\mathbf{x}[/itex] axis and [itex]\mathbf{y}^{\prime}[/itex] axis be parallel to
[itex]\mathbf{y}[/itex] axis. Now I will let this new frame's origin go around unit circle with no change in the direction of [itex]\mathbf{x}^{\prime}[/itex] and [itex]\mathbf{y}^{\prime}[/itex] axis. So will this be a translating frame or rotating frame with respect to the fixed frame. I think its a translating frame, since the axes are not changing directions. Am I right ?
thanks
