Review of Universal Gravitation
... the burn is quick and we can assume that the rocket did not change position during the burn. So the total energy E new > E old (Enew will be less negative) . Therefore, the satellite will no longer follow equation (1) and will not be in circular orbit at that same instantaneous radius. Instead the s ...
