This is a statement in my book - "The relative velocity of a satellite moving in the direction of Earth's rotation (for an observer on earth) is given as Vs - Ve."
We always define relative velocity of a particle say P in a frame of reference S1 accelerating w.r.t to an inertial frame of reference say S as
VP,S1 = VP,S - VS1,S
But in this case the Earth itself has some angular velocity and it is not an inertial frame of reference. My question is, in the expression Vs - Ve, what is the inertial frame w.r.t to which we define these velocities? Is it Earth again or some other imaginary inertial frame ?
