Suppose we have a space ship orbiting the earth. What must happen in order for the spaceship to leave orbit and fall back toward earth?The spaceship will fall back toward earth on its own but you have to just wait for it to fall.The spaceship's forward motion must be slowed down so the earth's gravitational pull on it will be stronger than the ship's forward motion.The spaceship's forward motion must be sped up so the earth's gravitational pull on it will be weaker than the ship's forward motion.It is not possible for a spaceship orbiting the earth to leave orbit and fall back to earth once it is in orbit.
