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 earth
- The acceleration of S is always directed towards the centre of the earth
- The angular momentum of S about the centre of the earth changes in direction but its magnitude remains constant
- The total mechanical energy of S varies periodically with time
- The linear momentum of S remains constant in magnitude
Answer
(A) The acceleration of S is always directed towards the centre of the earth
