Earth rotates eastward, in prograde motion. As viewed from the northern polar star Polaris, Earth turns counterclockwise. The North Pole, also known as the Geographic North Pole or Terrestrial North Pole, is the point in the Northern Hemisphere where Earth's axis of rotation meets its surface. This point is distinct fr…

Eventually they stop rotating altogether. In such a situation we sometimes assume that the angular acceleration of the blades is constant and apply the equations of rotational kinematics as an approximation. thunder palit
