WHEN A PLANET MOVES AROUND THE SUN, ITS
(A) AREAL VELOCITY IS CONSTANT
(B) LINEAR VELOCITY IS CONSTANT
(C) ANGULAR VELOCITY IS CONSTANT
(D) ALL THE VELOCITIES ARE CONSTANT
The option B is correct
A) areal velocity is area covered per unit time. So, it can not be const. in this case since the earth revolves the sun in an elliptical orbit.
B) Liner velocity is constant since the distance covered per unit time is same.
C) Angular velocity is different since the angles keep on changing in an elliptical path.
