Rotation of Earth and Its Effects

Q. What is the difference between angular velocity and tangential velocity?

1. Angular velocity is the same for all points on Earth, while tangential velocity decreases from the equator to the poles.
2. Tangential velocity is the same for all points on Earth, while angular velocity decreases from the equator to the poles.
3. Angular velocity is the same for all the points on Earth, while tangential velocity increases from the equator to the poles.
4. Angular velocity is not the same for all points on Earth, while tangential velocity decreases from the equator to the poles.
