Towing momentum towards the center of the world decreases in direct proportion to the distance. It is zero in the center. On the surface of the earth, it may change according to the location with gravity. For example, as you go from the equator to the poles, the acceleration of gravity increases and reaches the maximum gravity acceleration at the poles. The reason this;
• It is the shape of our world. Since the earth has a bulging structure from the equator, which is flattened from the poles, the distance from the poles to the center is less. therefore, the acceleration of gravity at the poles is higher.
• Another reason is that the simultaneous linear velocities of the two objects at the equator and poles are different from each other. The object in the equator moves physically faster as it has to travel more than the pole at the same time. Accordingly, the acceleration of gravity in the equator is less.
While the acceleration of gravity in the equator is 9.78 N / kg, it is 9.81 N / kg at the poles.
