defining velocity for elliptical orbits

RolandIRL · 2010-04-09 17:44:58

hi all, doing a bit of applied maths study for exams. going through orbits of planets and satellites at the moment. just wondering how would you define velocity for a satellite in orbit around Earth, specifically at R(max) and R(min). sifted through my notes but can only find V(max) at R(min). V(max) = (1+e)(GM/L)^1/2 ,…

hi all,
doing a bit of applied maths study for exams. going through orbits of planets and satellites at the moment. just wondering how would you define velocity for a satellite in orbit around Earth, specifically at R(max) and R(min).
sifted through my notes but can only find V(max) at R(min).

V(max) = (1+e)(GM/L)^1/2 , where e is the eccentricity,
and L = R(min) (1+e)

how would you define velocity for elliptical orbits?

thanks
