Wolfram Demonstrations Project

Have you ever wondered about your linear speed at your latitude on the Earth? Just move the slider to find out!

The radius of the Earth is

and its angular velocity (the angle covered per second) has a value of

. The linear velocity can be computed as

and is equal to

as a function of the angle

corresponding to the latitude.

For more details, see the Wikipedia entry for Latitude.
