Angular Speed of Earth's rotation
By: - Dr.A.S.Kalra Astrologer
Angular Speed of rotation of Earth: -Earth rotates from West to East on its axis and it takes 24 hours in completing one rotation around its axis which means it rotates by 360° in this time interval of 24 hours.
One rotation (360°) finishes in 24 hours or 24 × 60 minutes
360° = 24 × 60 minutes
1° = (24 × 60 minutes) / 360° = 4 minutes
This way Earth would take 4 minutes in rotating through 1° and which is its angular speed of rotation around its axis .
