Coriolis Definition and 179 Threads

according to the figure attached below , do we have a coriolis acceleration on the slider and why ? why can't we say that it is a centripital acceleration ? I want to know the difference between coriolis accelration and centrepetal acceleration , cause As I know , coriollis...

Prompted by D H's post on inertial forces … … I've just read the fascinating wikipedia article on http://en.wikipedia.org/wiki/Fictitious_force" . I hadn't previously understood how important Coriolis force is, even over small distances. :redface: Coriolis force is (minus mass times)...

The following problem is take from Thorton and Marion's Classical Dynamics, 5th edition, p. 408, chapter 10, problem 3. Given A puck of mass m on a merry-go-round (a flat rotating disk) has constant angular velocity \omega and coefficient of static friction between the puck and the disk of...

I was wondering if anyone could debunk or prove the theory of a Galactic Coriolis effect. That is, that stars and planets rotate one way in one hemisphere of the galaxy, and rotate in the opposite direction in the other hemisphere, similar to how the swirling of water is affected in the...

Has the Coriolis force affected continental drift (or the flow of Earth's interior) significantly over the history of the Earth? If so, how might the shape of continents today demonstrate this?

Show that the Coriolis force makes the puck move in a circle as seen in Earth's rotating frame I need help setting this up! Homework Equations -2m\varpix v The Attempt at a Solution So far i have a drawing The Earth on an xyz axis, z up, y across, and x in an out of paper. the puck is on...

Homework Statement If you project a particle vertically upward, and you neglect everything except gravity and the Coriolis acceleration, my book says that it will not land on the point where you projected it. Why does this make any sense since the Coriolis force should be antisymmetric on the...

Homework Statement A plane with a fully laden mass of 500 tonnes is flying due north at a steady speed of 1000kmh^-1 and is located at a latitude of 51 degrees north at a specific time. What force in an east-west direction is required to keep the plane on course along a fixed line of...

Homework Statement A river of width D flows Northward with speed v. Show that the water is lower at the west bank than at the east bank by approximately 2Dwvsinlamda/g where w is the angular velocity of the Earth and lamda the latitude. Homework Equations The Attempt at a...

When you stir a cup of tea with leaves at the bottom then when you stop stirring the leaves go to the center. I always thought that the cause was the centrifugal force and since the leaves where lighter than the water the water was pushed out and the leaves sucked in. But I just read in SA...

We've all heard that water spirals down the drain in a clockwise direction in the Southern hemisphere and counter- (or anti-) clockwise in the Northern hemisphere, due to the Coriolis effect from the rotation of the Earth. I've also heard that this is a myth, and that if you calculate the...

I've been searching all over the web and on this forum for an answer, and I haven't found it (or I may have found it and not understood...). If this is a re-hash, I'm sorry... I'm working on some ballistics calulations for long range rifle shots. I've got pretty much everything worked out...

I think that this is the proper place for this, but move it if I'm wrong. I'm conducting a physics project that has to do with what I think is the coriolis effect and simple harmonic motion. If a free swinging pendulum is let swing from a point over a level sand pit, as it swings, it will...

Galileo observed that objects dropped from height hit ground to the east of a plumb bob. I guess this is due to the Coriolis force. How would this distance be calculated for something like a baseball off the Empire State Building or a skydiver?

I need some help,... On the surface of the Earth a cartesian coordinate system _E will be installed at the latitude ϕ. The axes of the coordinate system are aligned as following: _x1-axis: points up _x2-axis: points north _x3-axis: points east The underscores in front of the variables...

1) what is the radius of the circle as a function of V for the coriolis force? --- is it R = (1/F)(- 2 m V^2)...am I missing something here please help... 2) Evaluate this radius for object on surface of the Earth at 33 degree north moving at 5 mph. and find the magnitude of Coriolis force...

I know that some people worship Symon's Mechanics 3rd Ed., but I find this book incredibly confusing...especially chapter 7, dealing with rotating coordinate systems. I follow the math, and perhaps the logic, but I can't even find a way to start the homework problems. The guy doesn't give any...

Arne wants to move in Leuven (54°N) with such a high speed that the vertical component of the Coriolis force cancels out the gravitational force. In which direction should he move to keep his speed as small as possible? How big is this speed? How big is the horizontal component of the Coriolis...

According to Wikipedia, the shells of the Paris Gun fired over 120 km landed "1,343 meters (4,406 ft) to the right of where it would have hit if there were no Coriolis effect"... Is it then correct to say that it would have deviated by 134.3 metres over 12 km, and 13.43 metres over 1.2 km etc...

hi, i read lots of book regarding fictitious force - coriolis and centrifugal forces, but i am not clear how to determine the direction of the force.. example. if we throw a ball vertical up , how we can know the deviation from the original position ( from book we know that if the ball...

How does GR account for coriolis forces on a solid spherically symmetric body in a frame of reference where the solidy body rotation has been eliminated? Are these trajectories inertial, as in if a free falling object has an initial velocity along the angle between the plane of rotation and...

I have this assignement (due tomorrow by the way) where I must compare the range of a projectile on the non-rotating Earth with the range of the projectile on the rotating earth. The question reads: I asked the teacher and he said that the range is rather small, so we can consider the Earth...

Ok I'm having some general problems with solving Coriolis problems. So the general way of writing up the Coriolis force is F_c = -2*m*(\vec{\omega} \times \vec{v}) But most questions i get about the Coriolis force involve some information about it's latitude position on earth, but i...

What is Coriolis Force & what are its applications?

why doesn't Coriolis force affect the wind speed but only the wind direction?

A projectile is fired nearly horizontally at high velocity v_0 toward the east. (a) In what direction is it deflected by the Coriolis effect? (b) Determine a formula for the deflection is terms of v_0, the angular velocity \omega of the earth, the latitude \lambda where the projectile is fired...

Hi all. Please excuse my tendency to over generalise There is some theorising going on and certain evidence to suggest that gravity may actually be polarized. Some scientists are looking at our weather patterns for instance and the well known Coriolis effect. Some now suggest that gravity is...

After careful observation of tornado funnels and coriolis generated water funnels of draining sinks the increasing angular velocities of the water with reduced radii is greater than allowed for by the law of conservation of angular momentum. Could someone shed some light on this situation...

If the coriolis effect does not determine the direction in which water drains down a plug hole in different parts of the world then is it totaly random which way the water spins.
