Question

Which among the following statements is true about the tangential and angular velocity of the Earth?

• A. Earth's angular velocity decreases from the poles to the Equator.
• B. Earth's tangential velocity remains same for each point on Earth.
• C. Earth's angular velocity remains same for each point on Earth.
• D. Earth's tangential velocity decreases from the poles to the Equator.

Answer 1

The correct option is C Earth's angular velocity remains same for each point on Earth.

The angular velcity of Earth remains the same for every point on the Earth. The angular velocity of Earth is 0.00418° per second. The tangential velocity of Earth decreases from the Equator to the poles. The tangential velocity of Earth is 1674.4 km per hour at the Equator.
