A satellite S is moving in an elliptical orbit around the earth. The mass of the satellite is very small compared to the mass of the earth.

  1. the angular momentum of S about the centre of the earth changes in direction, but its magnitude remains constant
  2. the total mechanical energy of S varies periodically with time
  3. the linear momentum of S remains constant in magnitude
  4. the acceleration of S is always directed towards the centre of the earth
