Centrifugal force is a force that appears to push items outwards from the center of rotation in a frame of reference that is rotating But the object in a rotating frame tend to move in a straight line following Newton s first law of motion However because the frame is rotating it appears as if a force is pushing objects outward
The main force causing the above phenomena the movement of the continents and especially the direction they move in as well as the upper part of the magma in the mantle is the centrifugal force
Centrifugal force is not a real force but a so called pseudo force It arises out of the attempt to analyze motion within the framework of Newton s laws but from the point of view of a rotating frame of reference An example is the description of atmospheric motion from a reference frame on the Earth which is of course rotating
centrifugal force as illustrated in gure 2 Gravitational force however will vary because the distance between these points to the Moon may vary by up to one Earth diameter Gravitational force will prevail over centrifugal force on the hemisphere closest to the Moon and centrifugal force will prevail on the hemisphere furthest to it
When an ion is deflected by a magnetic field Figure 5 the centripetal force caused by the deflection of the ion beam by the magnetic field = HeV must exactly balance the centrifugal force that results from the ion beam being caused to travel in a circular trajectory of radius r =mv 2 /r Only ions for which this balance is achieved will traverse from the entrance to exit slits of the
It is a centrifugal force that arises when the car moves along a curved path This force pushes me against the right side of the car Both arguments are valid descriptions of what happens however we mustn t forget that the centrifugal force is a fictitious one The only real force in this example besides gravity is the centripetal force
Because the centrifugal force does not change with location yet gravitational attraction does we can compute the tide generating force as the difference between the Moon s gravitational pull at the center of the Earth a force equal to the centrifugal force but easier to use in the following equations and the Moon s gravitational pull
$begingroup$ Not a full answer as I lack time but Centrifugal force does have an effect on apparent gravity both in magnitude and direction This is because the force due to gravity is towards the centre of the earth but the centrifugal force is away from the earth s axis of rotation so unless you re on the equator the two vectors are not exactly opposite in direction
zero The only apparent force is the centrifugal force and this causes the radial component of the velocity to become nonzero Therefore the kid sees the ball come off the merry go round at right angles as seen by the kid Then since the radial component of the velocity is positive the coriolis force points in the − θˆ direction and the
After the initial adjustment in water surface slope is made the centrifugal force has no further direct effect on the movement of the water relative to an observer riding on the turntable Lakes and oceans on Earth adjust in this same way—as does the solid Earth itself It is the reason why the Earth is an oblate spheroid with equatorial
Example PageIndex{1} What Coefficient of Friction Do Car Tires Need on a Flat Curve Calculate the centripetal force exerted on a 900 kg car that negotiates a 500 m radius curve at m/s Assuming an unbanked curve find the minimum static coefficient of friction between the tires and the road static friction being the reason that keeps the car from slipping see Figure
If it would rotate fast enough to throw a person off it would throw everything off dirt houses cars etc as the mass of an object is irrelevant the centrifugal force pulling out and the gravitational force pulling in are both proportional to an object s mass Basically the whole thing would explode out at the same time
$begingroup$ The idea was that flipping the direction of the centripetal force vector from 1 to the Earth at any point in time would create a new vector that is centrifugal to Earth and hence the rotation axis but centripetal to 1 This would be the exact acceleration needed to describe Earth s rotation from 1 s perspective considering 1 always sees the Earth 180° ahead
$begingroup$ The magnitude of the force is smaller than the variation in g the centrifugal force is about % of g $endgroup$ Martin Beckett Commented May 12 2011 at 5 12
Then on a spinning sphere the centrifugal force an outward force that arises from the spinning pushes the puck toward the equator After traveling about 50 miles north the puck reverses its
force due to in moving from to where one often takes The gravitational potential is the potential energy in the field due to per unit mass In other words it s the work done by the gravitational force per unit mass One can define as either the positive or negative of the work done which translates in a change of sign Beware
There s also the centrifugal force and also in a small area at the surface of the Earth it is correctly approximated in a very similar way constant direction; proportional to mass with a proportionality coefficient that is constant at a given latitude $$vec{F} c=momega^2R Tcos lambda vec{u}$$

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 the two forces there are roughly at right angles Nevertheless the entire earth is in an isostatic equilibrium that
Effects of Earth s Rotation Apparent Forces Newton s Second Law applies in an inertial reference frame which means that the reference frame is not accelerating
At all different latitudes on Earth you are always moving with the Earth s rotation perpendicular to the Earths axis Therefore the centrifugal force is always perpendicular to the axis The centripetal force of gravity always points towards Earths center not its axis
The net force on Earth causes it to orbit about the Earth Moon center of mass located about 1600 km below Earth s surface along the line between Earth and the Moon The tidal force can be viewed as the difference between the force at the center of Earth and that at any other location In Figure PageIndex{2} this difference is shown at
Can centrifugal force make you stick to a spinning ride No it s the normal force between you and the ride that keeps you in place not centrifugal force Is centrifugal force the same as centripetal force No centripetal force pulls an object towards the center of rotation while centrifugal force appears to push it away from the center
centrifugal force at the center of the Earth C is equal to that of the gravi ty due to the Moon Both forces point in opposite direction so that they balance each other and cancel Otherwise the Earth and the Moon cannot stay resting in the co rotating frame The red arrows are the vector sum of
