Suppose near the equator the person is sitting on a chair. He may not be doing any movement, but as shown in the drawing planet Earth near the equator moves at the speed of 1,525 feet/second. In an hour that would be 1,660 kilometers! Where even a static object moves at such a speed, if atmosphere itself remained static, what would be the effect? A terrible windstorm would be experienced with the wind blowing at the same speed – and how that would feel, just imagine!
