Why is gravity so small in Hudson Bay, Canada?

Because the mass of the area in Hudson Bay is less than the average mass of the Earth, because the mass is smaller, the force on the objects in the area is reduced, and the gravitational force is reducedAnyone who has studied physics in secondary school knows that gravity is the attraction that arises from another object on the earth due to the fact that the earth itself has a certain mass. Hence the magnitude of the gravitational force is determined due to the mass.

Generally speaking, an object with a large mass will have a greater attraction to other objects, and an object with a small mass will have less attraction to other objects. The existence of black holes is also based on this principle, because black holes are a sphere with a large mass and a large density, so it can attract many things, and even light can no longer break free when it enters the black hole. Canada's Hudson Bay can be said to be similar to the black hole theory, but the result is the opposite.

One is the phenomenon of gravitational force becoming larger, and the other is the phenomenon of decreasing gravitational force.

Because the earth is not a particularly perfect sphere, its surface is uneven, so the average mass of some of the sunken parts of the earth is less than that of the rest of the place. It is also because of the fact that in Hudson Bay, Canada, the binding effect on objects in this area is weaker than the average binding effect in the rest of the earth. That's why the gravity in the area is smaller.

It is precisely because of the wonders of nature that we are fortunate enough to encounter such interesting scientific phenomena. For the earth, we can now say that we humans have a little understanding, but there are more mysteries waiting for us to explore.

This phenomenon is quite interesting. If you live in a place with less gravity, will you walk more briskly? If the earth's restraint on us is reduced, to a certain extent, can we achieve a body as light as a swallow?

The reason why gravity is so low in Canada's Hudson Bay is because the snow cover from the last glacial period, which melted 10,000 years ago, thinned the local crust and made the gravitational pull smaller.

As far as I know, the reason why there is so little gravity in Hudson Bay in Canada is because in Hudson Bay, Canada, it is located at a very small latitude, so at this latitude, the gravity on Earth is very small.

Gravity in some places due to the rotation of the Earth.

It is relatively small, and you may learn about it when you study celestial motion, and you will learn more about it when you think about the rotation of the earth.
