1.	A comet orbits the sun in a highly elliptical orbit. Does the comet have a constant? 1. linear speed, 2. angular speed, 3. angular momentum, 4. kinetic energy, 5. potential energy, 6. total energy throughout its orbit? Neglect any mass loss of the comet when it comes very close to the Sun.
Answer» 1. No, linear speed varies from point to point in the orbit. 2. No, angular speed varies from point to point in the orbit. 3. Yes, angular momentum is conserved at any point 4. No, kinetic energy varies as the speed varies. 5. No, potential energy varies as distance, from Sun varies. 6. Yes, the total energy of the system is always constant.

A star 2.5 times the mass of the sun and collapsed to a size of 42 km rotates with a speed of 1.2 rev. per second. (Extremely compact stars of this kind are known as neutron stars. Certain stellar objects called pulsars belong to this category). Will an object placed on its equator remain stuck to its surface due to gravity? (mass of the sun = 2 × 1030 kg).
