The mass of the earth is not great enough to force itself into a perfect sphere. This is because the motion of the earth rotating forces the centre to bulge outwards. As the rotation of the earth slows down, so does the bulge at the equator.
The gravitational acceleration will decrease slightly as you move from the equator to the poles due to the Earth's shape (oblate spheroid). This is because the centrifugal force is greater at the equator compared to the poles, which causes a slight decrease in the net gravitational force experienced at the equator.
No, centrifugal force is greater at the poles than at the equator because the Earth's rotation causes a bulging effect at the equator that counteracts the centrifugal force. This is why objects weigh slightly less at the equator compared to the poles.
The earth is not a perfect sphere. The spin of the earth causes it to buldge out at the equator, which means the equator is further from the center of the earth then the poles are. The further an object is from the center of mass of another object, the less effect the gravity of those objects will have on each other. So at the equator, an object is being effected less by the gravity of the earth then it is at the poles.
The weight of an object is less at the equator compared to the poles due to the centripetal force produced by the Earth's rotation. At the equator, this force partially counteracts the force of gravity, effectively reducing the object's weight. This difference in weight is more noticeable for objects with larger mass.
The main reason a person weighs less at the equator than at the poles is due to the centrifugal force exerted by the Earth's rotation. This force is stronger at the equator because of the greater distance from the axis of rotation, effectively counteracting a small portion of the gravitational pull.
The radius at the equator is 3,963 miles. It's slightly less through the poles.
The radius of the earth is about 3,970 miles at the equator, a little bit less from the center to the poles.
The gravitational acceleration will decrease slightly as you move from the equator to the poles due to the Earth's shape (oblate spheroid). This is because the centrifugal force is greater at the equator compared to the poles, which causes a slight decrease in the net gravitational force experienced at the equator.
since gravity is inversly proportional to square of radius. Gravity increases with equater to poles. Gravity is high on poles and less on equator
Rotation.

Because the middle of the earths surface is the hottest on earth and the equator is right in the middle and the poles is at the end of the earths surfaces
Well the above question is not true, The same object will weigh less at the equator than at the poles (of Earth). The force is the force of gravity and the effect is because the object placed at the poles will be nearer the center of the Earth than at the equator because the Earth is an Oblate Spheroid.
no, we do not weigh the same at the poles because as the earth is not perfectly round and is like an orange, the distance between the object and the earth's core is less due to which we weigh more on poles
no, but the electromagnetic field of the earth does.
