Relative Motion – Earth's rotation and centrifugal acceleration
Solution: Centrifugal acceleration. The centrifugal acceleration is given by:. Where ω is the angular velocity of the earth and r is the position vector with respect to O' (a non-inertial reference frame) of the point where we are calculating it. First we are going to calculate the magnitude of the centrifugal acceleration as a function of the latitude λ:

Centrifugal force - Wikipedia
Earth's gravity is a bit stronger at the poles than at the equator, because the Earth is not a perfect sphere, so an object at the poles is slightly closer to the center of the Earth than one at the equator; this effect combines with the centrifugal force to produce the observed weight difference.

Can centrifugal force inside Earth's outer core overcome gravity?
On the surface of the Earth the net force (centrifugal + gravitational) is strongly inwards and is roughly constant. As you descend into the earth, both the centrifugal force and the gravitational force decrease roughly in proportion to r. So gravity will continue to strongly dominate. The situation is a little different near the poles since ...

Centrifugal Force - The Flat Earth Society
Centrifugal force is the force term, sometimes called a "fictitious force" that you get when doing newtonian mechanics in a rotating reference frame. Centripetal force is a real force, and it is the force that causes an object moving in a circle to maintain it's circular motion.

The Rotating Earth - NASA
To derive the centrifugal acceleration on the equator (i.e. the force in Newtons on one gram mass, rotating with the Earth), we calculate in meters and seconds v2 / r = (465.1)2 / 6378000 = 216318 / 6378000 = 0,03392 m/s2 Comparing this to the acceleration of gravity--say 9.81 m/s 2 --it is only 0.00346 or 0.346%.

Answer (1 of 2): Ahh, that would be zero. If the Earth were stationary, you would need a normal force outward from the surface to keep you from accelerating into the center of the Earth. Because there is a rotation of about .04 m / s^2, you use about 1/2 of …

Centripetal Force and the Rotation of the Earth
This means that there must be a net force on you - the centripetal force pointing toward the center of the Earth. Therefore, the downward weight force must be greater than the upward scale force, and the difference between the mg force and the scale force equals the centripetal force on you! You weigh less because the Earth is rotating!

Centrifugal force - Wikipedia
Centrifugal force is the apparent outward force on a mass when it is rotated. Since Earth rotates around a fixed axis, the direction of centrifugal force is always outward away from the axis, opposite to the direction of gravity at the equator; at Earth's poles it is zero.

The so-called centrifugal force is indeed a fictitious non-existing force in the inertial frame. But the centrifugal effect is very real. That effect is causing the bulging. The counter-intuitive thing is just that it is not a centrifugal force which is causing the centrifugal effect. Rather, the cause is inertia. Think of your stone-in-a ...

Centrifugal force? Why does the Earth bulge at the equator?
FactChecker said: Coriolis force is at right angles to the centrifugal force and is caused by a different velocity. It is zero if there is no change in the distance from the object of interest to the axis of rotation. Coriolis force is perpendicular to the velocity (in the rotating frame), not to the centrifugal force.
