At which colatitude $\theta$ is the error between $\vec g_{eff}$ and $\vec g$ maximum? [closed]
Suppose a plumb bob hangs without swinging, then the string defines the
effective direction of gravity. Suppose you are holding the bob on the surface of the
earth at colatitude $\theta$, where $\...

Can we feel weightless if Earth's angular velocity is big enough? [duplicate]
According to Fn=Fg-Fc , if earth's angular velocity is big enough to make Fc equal to Fg, would we feel weightless?
I did some basic calculation earth has to rotate at 1 rev/5064s at equator for Fc to ...

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 ...

Centrifugal force on objects rotating around Earth
Suppose two objects travel around the equator on Earth at the same speed, $v$, in opposite directions, where the speed $v$ is measured relative to the Earth's surface. Will they experience different ...

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 ...

Does Earth's Rotation Affect Its Shape?
The question I am working on is, "Consider the following.
(a) Find the angular speed of Earth's rotation about its axis. rad/s
(b) How does this rotation affect the shape of Earth?"
I am ...
