Why can’t we feel the earth rotating ?
In: Physics
Because the centrifugal force from the rotation is quite small and constant for a single location. On the equator where is largest, it is only 0.3% of gravity and on the poles the force it zero. It and the difference in earth radius that change gravity have a measurable effect because the weight differs by 0.5% between the poles and equator.
In any location in between it changes the direction of down slightly.
A human would not feel the difference if your travel between the equator and poles but even a cheap precision scale would detect it.
the centrifugal force is the same as if you drive a car in a circle with 50 meters (164 feet) radius and each lap takes 4 minutes.
So the forces from the rotation is quite a small constant ins strange and direction so it is is like a slight change in gravity.
