Would you expect the total energy of the solar system to be constant? What about the total angular momentum? Explain |
| Answer» Yes, The gravitational force is conservative. When a system is under the action of conservation forces, its total energy (kinetic `+` potential) is constant and hence, the energy of the solar system is constant. The gravitational forces on planet of the solare system are central forces directed towards te sun and hence, the moment of forces about the sun is zero. Thus, not torques acts on the planets and the angular momentum is constant. | |
