Question

What is the difference between angular velocity and tangential velocity?

• A. Angular velocity is the same for all points on Earth, while tangential velocity decreases from the equator to the poles.
• B. Tangential velocity is the same for all points on Earth, while angular velocity decreases from the equator to the poles.
• C. Angular velocity is the same for all the points on Earth, while tangential velocity increases from the equator to the poles.
• D. Angular velocity is not the same for all points on Earth, while tangential velocity decreases from the equator to the poles.

Answer 1

The correct option is A Angular velocity is the same for all points on Earth, while tangential velocity decreases from the equator to the poles.

Angular velocity is the same for all points on Earth, while tangential velocity decreases from the equator to the poles. So, for an object rotating about an axis, every point on it has the same angular velocity. The tangential velocity of any point is proportional to its distance from the axis of rotation.
