WebMay 20, 2008 · Kepler's Third Law for Earth Satellites The velocity for a circular Earth orbit at any other distance r is similarly calculated, but one must take into account that the force of gravity is weaker at greater distances, by a factor (RE/r)2. We then get V2/r = g (RE r)2 = g RE2/r2 Let T be the orbital period, in seconds. WebKnow what Kepler's 3 laws are. 1) The paths of planets are ellipses with the sun at a focus. 2) An imaginary line from the sun to a planet sweeps out equal areas in equal times. 3) The square of the ratio of the periods of two orbiting bodies is equal to the cube of their radii ratio. → RATIO EQUATION. Know the motion of orbiting bodies.

WebKepler's Third Law From the above we can compute semi-major axis = perihelion + aphelion 2 = 1 2( 1 GM / c2 + A + 1 GM / c2 − A) = GM / c2 (GM / c2)2 − A2. We want to relate this to the orbital period T, the time it takes the planet to complete an orbit. In the section "Kepler's First Law," we deduced that the area swept out in a time t was ct / 2. http://spiff.rit.edu/classes/phys440/lectures/kepler3/kepler3.html earth-138
