What is the relationship between the deflection force of the floor tiles and the direction of the ob

Objects moving on the Earth are subject to geostrophic deflection forces (except those on the equator), objects north of the equator experience geostrophic deflection forces that are to the right of the direction of motion, objects south of the equator are subjected to geostrophic deflection forces that are more than left in the direction of motion, and objects on the equator are not subject to geostrophic deflection forces. This is similar to the motion on the surface of a rotating sphere, which is deflected only because of the frame of reference. In real life, we can also see that when the hole of the washbasin is drained, the water rotates counterclockwise; The shoes we wear on our right foot are also more likely to wear out than those we wear on our left foot.

These are all geostrophic deflection forces that are "playing tricks".

It will be faster, but this force is not due to the motion of the object, but is a manifestation of inertia, like centrifugal force.

The geostrophic deflection force is actually a surface geometry problem. The surface of the earth is a spherical surface, so everything moving on the surface of the earth, including wind, should move at a uniform speed along the trajectory of the great circle without external force (the great circle of the sphere is equivalent to the straight line of the plane), and among all the latitude coils of the earth, only the equator is a great circle, and the direction of the objects moving along the equator is unchanged; In other latitudes, if the object is still moving in a great circle, it will definitely change the latitude of the object, as if it is subjected to a force, but in fact there is no force that changes the direction of motion, but the sphere of the earth is responsible for all this.

As the wind speed increases, the latitude changes faster, and the geostrophic deflection force seems to be greater.

The Southern Hemisphere is biased to the left in the direction of movement of the object, and the Northern Hemisphere is biased to the right in the direction of movement of the object.

The problem is too unclear, I don't understand the problem.

Analysis: From the perspective of Newtonian mechanics, it can be assumed that the inertial force does not actually exist, but that it is a covariant transformation between the inertial and non-inertial frames—for example, the imaginary force generated by the Galilean transform and the Holorentz transform.

From the perspective of general relativity, both inertial and non-inertial frames are relative, so the inertial force is equivalent to the gravitational force, which is the basic property of matter and space-time, and both actually exist.

The "geostrophic deflection force" is generally referred to as the Coriolis force, or Coriolis force for short. According to Newtonian mechanics, in a rotating frame of reference, when there is a radial component in the direction of motion, or there is an apparent acceleration Apparent force, apparent acceleration is equal to the angular velocity of rotation multiplied by the radial velocity of motion, and apparent force is equal to apparent acceleration into the mass of an object. When the direction of motion is far from the axis of rotation, the apparent acceleration force is opposite to the direction of rotation; Otherwise, it is the same as the direction of rotation.

In the case of the earth, the Coriolis force is very small because the angular velocity of rotation is very small (2pi 86400 approx.), and the motion of a hidden object can be ignored. Claims such as "trains drive on the left to avoid collisions caused by Coriolis forces" are pure pseudoscience. The corresponding calculation is:

Assuming that the speed of the train at 45% north latitude is 100m s (360km h is faster than that of an airplane), the Coriolis acceleration is only about 100 * or so, which is about 5/10,000 of the gravitational acceleration, that is, if the error of the rail level exceeds 5/10,000, the impact will be greater than that of the Coriolis force, which cannot be achieved by the construction level. In fact, there is no need to calculate this kind of problem: how to say that the car is also more affected than the train (the train still has the railroad tracks), why does the car go to the right?

The properties of the horizontal geostrophic deflection force are: 1) The horizontal geostrophic deflection force is an inertial force due to the rotation of the earth, which is only generated when the air moves relative to the ground.

2) The direction of the horizontal geostrophic deflection force is perpendicular to the direction of air motion.

In the Northern Hemisphere, it points to the right of the direction of air motion, deflecting the air to the right of the original direction of motion.

3) Because the horizontal geostrophic deflection force is perpendicular to the direction of air motion, therefore, it can only change the direction of air motion, but not the rate of air motion.

4) The magnitude of the horizontal geostrophic deflection force is proportional to the wind speed and the sine of the latitude where the moving air is located.

The reasons for the influence of geostrophic deflection force on the direction of motion of horizontally moving objects are briefly described as follows: in order to maintain horizontal inertial motion, the graticule generates relative acceleration due to the rotation of the earth. The following is the popular explanation given by "Counting Like a Stream" The first thing to explain is that the geostrophic deflection force is to the right in the northern hemisphere, and to the left in the southern hemisphere, of course, these right and left are relative to the direction of progress, and the following is the situation in the northern hemisphere.

1.Since the angular velocity of each latitude is the same, when flying from north to south, the circle of the south is large, so the linear velocity is large, so a small linear velocity in the north is slower than the linear velocity of the south, so it deviates to the right due to inertia. It's the same with going north, from a fast place to a slow place, the speed is 'ahead', and the direction of progress is also deviated to the right.

2.Fly along the latitude to the east and west, at this time, because the direction of gravity points to the center of the earth, and the direction of the latitude circle points to the center of the circle is not the center of the earth, you can think about it, so because of this angle, the centripetal force can not completely cancel out the centrifugal force that you rotate around the center of the circle of the parallel, so a synthesis, it will also deviate to the right. 3.

The equator is not subject to geostrophic deflection precisely because the center of the earth is exactly the center of the circle in which the latitudinal circle rotates, and the two coincide, and gravity can cancel out the outward force. Finally, the geostrophic deflection force is greatest at the north and south poles.

If you're researching geography, don't bother, just remember the conclusion and be able to apply it.

To put it simply, the Earth rotates counterclockwise over the Northern Hemisphere, and the object deviates to the right in order to maintain horizontal inertial motion. In contrast, the southern hemisphere rotates clockwise (in China, people in the other hemisphere live on the earth with their brains downward), and the object deviates to the left in order to maintain horizontal inertial motion.

What are you talking about, be clear, and it's very doubtful that the compensation should be on the right, what does it mean?

The Rioli effect causes the wind to turn to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. This effect is most pronounced at the poles and disappears at the equator. Without the rotation of the Earth, the wind would blow from the polar high pressure to the equatorial low pressure region.

The Coriolis effect is most pronounced at the poles, gradually weakening towards the equator until it disappears at the equator. This is why typhoons can only make clouds form in areas above 5 latitudes.

Everything that moves on the earth is subjected to.

Geostrophic deflection force.

With the exception of objects at the equator, objects north of the equator experience a geostrophic deflection force that is to the right of the direction of motion, and objects south of the equator are subjected to a geostrophic deflection force that is far from the direction of motion, while objects at the equator are not subject to geostrophic deflection forces.

This is similar to the motion of a mountain on the surface of a rotating sphere, and the deflection occurs only because of the frame of reference.

In real life, we can also see that when the hole of the washing and teasing handpan is discharged, the water rotates counterclockwise; The shoes we wear on our right foot are also more likely to wear out than those we wear on our left foot. These are all geostrophic deflection forces that are "playing tricks".
