Assertion : Angular speed of a planet around the sun increases, when it is closer to the sun.
Reason : Total angular momentum of the system remains constant.

The angular velocity of earth around the sun increases when it comes closer to the sun. Why ?

When a planet moves around the sun

(A) : The angular velocity of a plantets orbiting around the sun increases when they are nearest to the sun. (R ) : The angular momentum of body is a proportional to angular velocity.

The linear speed of a planet around the sun is not constant in its orbit. Comment.

Assertion : In planetary motion angular momentum of planet about centre of sun remains constant. But linear momentum of system does not remain constant. Reason : Net torque on planet any point is zero.
