Galilean transformation Definition and 55 Threads

I'm having trouble with the 2nd part of this problem. By letter "d" I mean "partial," I wasn't able to preview latex, so I went without it. x=x'+V*t' (V is a constant) t=t' f=f(x,t) Part a ===== Find df/dt' and df/dx'. I got the following: df/dt'=df/dt+V*(df/dx) df/dx'=df/dx...

I need to show that the definition of linear momentum p=mv, has the same form p'=mv' under a Galilean transformation. What does it mean to "show" such a thing? I have no idea where to start :(

What happens if I have 2 frames,S and S', with S as my rest frame and S' moving in the +ve x direction (towards the right). Why is it that the equation for the galilean transformation for the x-coordinate is x'=x-vt instead of x'=x+vt ?

My problem is this: Let's say momentum is conserved in all frames... An observer on the ground observes two paticles with masses m1 and m2 and finds upon measurement that momentum is conserved. Use classical velocity addition to prove that momentum is conserved if the observer is on a train...

I just finished the first page of the URL at the motivation of my personal mentor, Doc Al. http://theory.uwinnipeg.ca/mod_tech/node134.html The writer showed examples of adding velocities using non photon entities. In using the photon in order to show that postulates of the speed of...
