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.

How the gravitational acceleration will change when you move from equator to north or south pole on the surface of earth?

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.


Is centrifugal force is more at equator than poles?

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.


Which best explains why the weight of an object is less at the equator than at 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.


Why is the weight of an object is less at the equator than 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.


A person weighs less at the equator than at the poles The main reason for this has to do with?

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.

What is the average radius of the earth?

The radius at the equator is 3,963 miles. It's slightly less through the poles.


What is the size of the earth according to radius?

The radius of the earth is about 3,970 miles at the equator, a little bit less from the center to the poles.

In which point gravity of earth is very high?

since gravity is inversly proportional to square of radius. Gravity increases with equater to poles. Gravity is high on poles and less on equator


What makes an object less at the equator than it is at the poles because of the Earth's?

Rotation.

Why do the poles receive the less solar energy than the equator does?

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


What is the force that dictates that objects weigh more at the equator than at the poles?

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.


Do you weigh the same on the Equator as you do at the poles?

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


Does gravity have a stronger pull at the eatrh poles then it does on the equator?

no, but the electromagnetic field of the earth does.
