Do you know your weight high in poles compare to equator?
Weight of any Object will be maximum in both north and south poles. This is happen because of high gravity force in poles. You can ask why gravity force is high in poles?. There is a reason behind in this, the distance between poles and Centre of the Earth will be less compare to the distance between the centre of the Earth and equator.so, less distance make high attraction of gravity force and high gravity force made an object to be more weight.so, weight of any Object will be more in poles.
