it is the rate of displacement on the axis per unit time of a point on the earth making circular motion. linear velocity is greatest at the equator due to the known physics of the earth and decreases towards the poles
speed for rating cartoonists among themselves.
linear velocity = (angular velocity)*(radical) v=w*r
earth rotates on its axis in 24 hours. so a day occurs. linear velocity is the distance traveled by the earth per unit time as it rotates around its axis.
