Is the normal force equal to weight if we take the rotation of Earth into account? [duplicate]
In my physics class we were doing problems such that we set $N$ (normal force) $= mg$. I understand that by Newton's Third Law, if I exert a force on the ground, then the ground will exert an equal ...

Why doesn"t centrifugal force throw us off the earth? [duplicate]
I was drawing a diagram and trying to resolve all the forces. It seems to me that because of gravity, centrifugal force will produce a sort of "dragging" motion along the surface of the earth. The ...

Do we feel the full force of the earths gravity even though the earth is spinning? [duplicate]
As far as I know, since the earth is spinning, centrifugal force should be throwing you off the earth. However, gravity counteracts that by being a stronger force. So if you stood an object with the ...

Net acceleration felt by a body on Earth [duplicate]
For any body on earth will the only acceleration it has be gravity or should we take into consideration even centrifugal force due to rotation?
Is there any precise formula to determine the net ...

Rotation of earth and effect on $g$ [duplicate]
How do we calculate the change in the acceleration due to gravity (consider earth as a uniform sphere) with a change in the rotation speed of earth along its axis?
How do we build up a mathematical ...

Why is the Earth so fat?
I made a naive calculation of the height of Earth's equatorial bulge and found that it should be about 10km. The true height is about 20km. My question is: why is there this discrepancy?
The ...

If the ground's normal force cancels gravity, how does a person keep rotating with the Earth?
When I am on earth, the weight of my body is countered by the reaction of the ground. So, there is no net force acting on me.
But I am spinning with earth. But if there is no centripetal force then ...

Why do we use kilograms instead of newtons to measure weight in everyday life?
What was the reason to use kilograms to measure weight (e.g. body weight, market vegetables etc.) instead of using newtons in everyday life?

Earth as a perfect sphere and an object trying to stand still
I have imagined the Earth as a perfect sphere with uniform mass density and I put an object somewhere between the equator and the north pole at rest with respect to earth. And also in my imaginary ...

Reaction force of the ground beyond the equator
Let's imagine a person standing somewhere on Earth, but not on the equator, i.e. somewhere with a positive net value of latitude.
Since the Earth spins around its axis and the person spins along, the ...
