Based on my observations, the earth rotates from west to east about the axis of rotation. The counter-clockwise rotation of the earth is as viewed from the North Pole star Polaris.
My observations supporting the counter-clockwise rotation of the earth are:
- The Sun rises in the east and sets in the west.
- All celestial objects including the stars and the moon rise in the east and set in the west.
The rotation is the result of the strong geomagnetic field of the earth. It is also responsible for the formation of day and night on the planet.

Theory because a theory has to be backed up by several experiments
The net force on the quarterback when he is hit by two linebackers running eastwards is 255N.
Force is a vector quantity, we must recall that if two forces act in the same direction, we obtain the net force by adding the two forces together. If two forces act in opposite direction, we obtain the net force by subtracting the forces from each other.
Since the both linebackers are running East, the net force is obtained as; 105 N + 150 N = 255 N.
