The Rotating Earth

Sep 22, 2004· The centrifugal force is a useful concept when figuring out equilibria in a rotating frame of reference, cases where forces balance exactly and no motion occurs To calculate motion in a rotating frame is much more complicated, and in general is beyond the level of this presentation...

Equatorial bulge

An equatorial bulge is a difference between the equatorial and polar diameters of a planet, due to the centrifugal force exerted by the rotation about the body's axis A rotating body tends to form an oblate spheroid rather than a sphere...

If the Earth Stood Still

If the Earth Stood Still Modeling the absence of centrifugal force By Witold Fraczek, Esri This article as a PDF The following is not a futuristic scenario...

Centrifugal force

In Newtonian mechanics, the centrifugal force is an inertial force (also called a 'fictitious' or 'pseudo' force) directed away from the axis of rotation that appears to act on all objects when viewed in a rotating reference frame The concept of the centrifugal force can be applied in rotating devices, such as centrifuges, centrifugal pumps, centrifugal governors, and centrifugal ,...

Coriolis force

When Newton's laws are transformed to a rotating frame of reference, the Coriolis force and centrifugal force appear , An important case where the Coriolis force is observed is the rotating Earth Unless otherwise stated, directions of forces and motion apply to the Northern Hemisphere...

Centripetal and Centrifugal Force

Centripetal and Centrifugal Force are the action-reaction force pair associated with circular motion Centripetal Acceleration Velocity is a vector - specifying how fast (or slow) a distance is covered and the direction of the movement Since the velocity vector (the direction) of a body changes when moved in a circle - there is an acceleration...

Centrifugal force

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...

Atmospheric Forces

The centrifugal force will try to pull air parcels outward if they are moving in a curved path around a ridge or a trough The magnitude of the centrifugal force is related to both the speed of the air parcel and the radius of curvature ,...

centrifugal force

The Earth's gravity is the acceleration caused by the attraction of the Earth's mass and the centrifugal force of the Earth's spin Every physical body (body that has a mass) experiences an acceleration caused by the Earth's gravitational attraction...

Math Forum

May 13, 2002· This force is the result of three forces: (1) gravity (acting downward), (2) centrifugal "force" (acting outward, perpendicular to the axis of the earth), and (3) the force of the ground pushing up on you (acting upward)...

Coriolis and Centrifugal Forces

forces due to the rotation of the earth This is what we were referring to in anearlier section, when we hinted that the surface of the earth is not really an inertial frame You will see that the , coriolis and centrifugal forces Keywords: rotation, noninertial forces, coriolis force, centrifugal force...

Centrifugal Force vs Centripetal Force

Centrifugal vs Centripetal Force Exampl Some common examples of centrifugal force at work are mud flying off a tire and children feeling a force pushing them outwards while spinning on a roundabout A major example of centripetal force is the rotation of satellites around a planet...

Tides and centrifugal force

But centrifugal force is a fictitious force, and we can't justify a real effect with a fictitious force, can we? The necessary and sufficient reason for the tides is the fact that over the volume of the earth, the gravitational force (from Moon or Sun) has different size and direction over the earth's volume as a result of the varying distance ....

Equatorial bulge

Most people sense that the Earth's equatorial bulge must be due to some kind of equilibrium, but recognizing what kind of equilibrium it is is not straightforward Very often people try to understand the bulge in terms of a force equilibrium: often there are statements about a balance between a centripetal force and a centrifugal force...

newtonian gravity

Because the rotation of the earth is very smooth and doesn't change, the centripetal acceleration we feel is very nearly constant This means that the (small) centrifugal force from the rotation gets added to gravity to make up the "background force,...

Earth's Gravity

Circular Orbit Gravity supplies the necessary centripetal force to hold a satellite in orbit about the earth The circular orbit is a special case since orbits are generally ellipses, or hyperbolas in the case of objects which are merely deflected by the planet's gravity ,...

Effect of centrifugal force on ocean and earth Centrifugal force acts on the ocean and earth It is pointed outward away from the rotation axis Therefore it is maximum at the equator (maximum radius , lecture_dynamics_rotationppt Author: Lynne ,...

Gravity and centrifugal force

The true gravitational force on a mass m points toward the center of the earth (or very nearly), the centrifugal force points outward from the Earth's axis, and mg is the sum of the two share | cite | improve this answer...

Frames of Reference: The Centrifugal force

The rest arises because the Earth is not a perfect sphere: the centrifugal force of its rotation causes its equator to bulge out, making the surface there more distant from the Earth´s center and thus weakening the gravitational pull...

Earth and centrifugal force

Mar 31, 2018· According to the current model of the earth, the globe is of course spinning much faster at the equator than the pol Because of this, due to centrifugal force, all physical objects should weigh less at the equator and more at the pol...

What Causes the Tides?

What Causes the Tides? By Lauren Cox, , the earth moves in a very slight circle too, and this movement is enough to cause a centrifugal force on the oceans (It's centrifugal force that holds ....

Apparent Forces

Apparent Forces are used to include the effects of an accelerating coordinate reference frame (eg rotation of the earth) Two apparent forces: Centrifugal force and Coriolis force Centrifugal Force Consider a ball attached to a string or length r, whirling around at a constant angular...

Does the Earth orbiting around the Earth

The centrifugal force is a fictitious force, a force that is not present in an inertial frame While fictitious forces can make for very handy calculating devices at times, they are not measurable precisely because they are a fiction...

Centrifugal Force vs Centripetal Force

The force the children feel is centrifugal force pushing them outward A common example for centripetal force is the moon or a manmade satellite orbiting the Earth The force comes from gravity, and is the same force allowing the planets to orbit the Sun...
