Question
Which is greater - angular velocity of the earth around its own axis or angular velocity of the earth around the sun?
Solution
Angular velocity of a body is given by,
where T is the time period of revolution.
Time period for earth to complete one rotation about its own axis is 24 hours (1 day).
And inorder to roatet about the sun, Earth takes 365 days. Therefore, angular velocity of the earth about its own axis is greater than that about the sun.
