WEIGHT IN THE POLES IS MORE THAN THE WEIGHT IN THE EQUATOR – WHY?
When the earth rotates, there will arise a ‘centrifugal force’ in it. This force will be ‘0’ in the poles and maximum in the equator. This centrifugal force’ will be against the gravitation force in each point in the earth. The difference between both will be the ‘actuating speed’ in each point of the gravitation force towards the center of the earth. In the poles, the ‘actuating speed’ of the gravitation force will be 980665cm/ second. In the equator , extra ‘centrifugal force’, there the ‘actuating speed ‘of the gravitation force in each second will be less in the rate of 3.39 cm. Therefore, force passed by earth on thing, there is no material mass. So, the gravitation force will not be the same and will not be equal in all the places. So, will for example, in the mountain areas, the gravitation force will be more. Thus, there is a theory that weight will be more in the poles than in the equator. But Is not correct to take it like that in practice .
