For a planet revolving around Sun in an elliptical orbit, to obtain its velocity at any point we have to apply

A planet is moving around the sun in an elliptical orbit. Its speed is

A planet is revolving round the sun in an elliptical orbit, If v is the velocity of the planet when its position vector from the sun is r, then areal velocity of the planet is

A planet is revolving round the sun in an elliptical orbit, If v is the velocity of the planet when its position vector from the sun is r, then areal velocity of the planet is

The earth revolves round the sun in an elliptical orbit. Its speed

The earth revolves round the sun in an elliptical orbit. Its speed

STATEMENT -1 : When a planet revolves around Sun in an elliptical orbit, the work done Sun's gravitational force on the planet remains zero for any value of displacement. and STATEMENT -2 : The mechanical energy of Sun planet system remains conserved throughout the motion of planet.
