Why the angular. speed of earth around sun increases when it comes near the sun ?

Text Solution

Verified by Experts

All planets revolve around sun in elliptical orbits as shown in figure keeping sun at one of its foci.
Angular momentum (L) = mvr
As `v = omegar`
So `L = momegar^2`
Now `omega = L/(mr^2)" "...(i)`
It is clear from equation (i) that angular velocity is inversely proportional to square of distance of earth from sun `(r^2)` When earth comes near to sun, due to decrease in value of r, angular velocity `(omega)` increases.
