A satellite is moving in an elliptical orbit around the Earth. If the mass of the satellite is very small as compared to the mass of the earth, then:
| 1. | The angular momentum of about the centre of the earth changes in direction, but its magnitude remains constant. |
| 2. | The total mechanical energy of varies periodically with time. |
| 3. | The linear momentum of remains constant in magnitude. |
| 4. | The acceleration of is always directed towards the centre of the earth. |
