A planet is revolving around the sun in an elliptical orbit. Which out of the following remains constant.
(a) Linear speed (b) angular momentum
( c) kinetic energy (d) potential energy (e) total energy throughout its orbit.

Text Solution

Verified by Experts

The correct Answer is:
All quantities vary over an orbit except angular momentum and total energy
Net torque on thhe comet is zero then the angular momentum is conserved
