Web13 mei 2016 · 1. The answer is Yes. – Serg. Nov 23, 2012 at 17:34. 1. @EMACK, definitely the rotation gives the Earth the shape of a disk, rather than a sphere. The distance to the Earth center is less on the poles than it's on the equator. It also affects the gravitation g that is measured at sea level on poles or equator. – Serg. WebWell, this is just the absolute value of our angular velocity. So we could say that speed is equal to the absolute value of our angular velocity. Absolute value of our angular velocity, times our radius. Times our radius. And now so this is super useful. Our speed in this case, is going to be pi over six radians per second. So pi over, pi over six. boerne area christian homeschoolers
