Not for sure but it seems like there would be more gravity at the equator than at the poles.
The earth rotates and creates a centrifugal acceleration at the equator the counters the force of gravity.
acceleration due to gravity =GM/R2
acceleration due to rotation =V2/R
So gravity at the equator is GM/R2 - V2/R

Why is the weight of an object is less at the equator than at the poles?
The weight of an object is slightly less at the equator than at the poles because of the earth's tilt on its axis.
Is the weight of a person or object much less at the poles than at the equator?
much less
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 does the weight of an object change when it is moved from the equator to the poles?
Because of centripetal acceleration you will weigh a tiny amount less at the equator than at the poles.
What makes an object less at the equator than it is at the poles because of the Earth's?
Rotation.
Why do an object weight less at the equator then at the poles?
less gravity pull farther away from central pole
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.
How does the earth rotation affect the measurement of the weight of an object at the equator?
Due to the centrifugal force caused by Earth's rotation opposing gravity for objects on the equator, objects there weigh about 0.5% less than they do on the poles. So an object that weighs 200 N at the poles weighs about 199 N on the equator.
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.
Why do poles receive less solar energy then the equator does?
The poles receive less solar energy then the equator does because the radiation from the sun has to pass through much more atmosphere to reach the poles than to reach the equator. During that transit, more of the energy is scattered on the path to the poles, and less reaches the ground there.
Do oceans near the poles tend to be saltier?
The water is saltier at the poles, and less salty at the equator.
