Centrifugal force, velocity, mass, inertia, gravitational force

Inertia is only about mass......

Inertial centrifugal force is a technical term in physics, which is an imaginary force introduced by the observer in the rotating frame of reference without knowing that the system is moving in a circular motion to explain the observed phenomenon, on the disc of the Aino clan that rotates the ground at a uniform speed, a small ball with a known amount of mass is connected to the center of the disc with a spring, and when the disc rotates at a certain angular velocity, the observer on the disc will find that the ball moves outward by the action of a force to elongate the spring. That is, the ball is subjected to a force that deviates from the center of rotation in one direction, and this force is caused by the inertia of the ball, so it is called inertial centrifugal force.

Centrifugal force is a virtual force or inertial force, which keeps the rotating object away from its center of rotation, when the object moves in a circle, the centripetal acceleration will produce a force-like effect in the coordinate system of the object, similar to a force acting in the centrifugal direction, so it is called centrifugal force.

Inertial centrifugal force is a physical term, is an imaginary force introduced by the observer in the rotational frame of reference in order to explain the observed phenomenon without knowing that the system is moving in a circular motion, on a disc that rotates at a uniform speed relative to the ground, a small ball of known mass is connected to the center of the disc with a spring, and when the disc rotates at a certain angular velocity, the observer on the disc will find that the ball moves outward by the action of a force to elongate the spring. That is, the ball is subjected to a force that deviates from the center of rotation in one direction, and this force is caused by the inertia of the ball, so it is called inertial centrifugal force.

Centrifugal force is a kind of virtual force or inertial force, which makes the rotating object away from its center of rotation, when the object moves in a circle, the centripetal acceleration will produce a force-like effect in the coordinate system of the object, similar to a force acting in the centrifugal direction, so it is called centrifugal force.

The explanation upstairs is a little rougher, please see my explanation.

First of all, it is important to note that centrifugal force is a force that does not exist, and it is an imaginary force. If the word comes from the mouth of a physics teacher, centrifugal force is an abbreviation of inertial centrifugal force, and if it comes from the mouth of an adult who has been out of school for many years and has a relatively average level of science, it is generally a misconception.

I wonder if the landlord played with large children's toys such as turntables when he was in kindergarten? Imagine that when a person is on a turntable, due to the rotation of the turntable, the person will feel a force pushing the person outward along the radius, but if the force analysis of the person's state at this time is carried out, the force that pushes the person outward cannot be found.

In physics, the reference frame of the ground and the uniform linear motion relative to the ground is called the inertial reference frame, referred to as the inertial frame, and the reference frame of the variable speed motion relative to the ground (including the variable speed straight line, uniform speed curve, and variable speed curve Hu Xun judgment) is called the non-inertial frame. This is because in an inertial frame, Newton's laws of motion are true, whereas in a non-inertial frame, Newton's laws of motion cannot hold.

The characteristics of this frame of reference are now analyzed using the example of uniform circular motion.

mg=f(n)=ma(n)=mv2 r (the lower corner of the letter is in parentheses).

The above equation is Newton's second law in uniform circular motion.

Now suppose that this object is ourselves, and when we take the disk as a frame of reference, we see that we are not moving, but always have no displacement at a certain position of the disk. Now let's take a look at the force: since we are "stationary", we should not be subjected to the force in the horizontal direction, or the force should also be affected by the equilibrium force.

But we feel that there is a "force" that pushes us outward, and if there is no force that balances with this "force", then we will slide out of the disk in the direction of the radius and out of the disk. So there must be a force that "holds" us, and that force is our friction with the disk, and the existence of this friction is recognized by another observer who uses the ground as a frame of reference, but the "force" that pushes us outward is not recognized by that observer. In this way, we find that Newton's first law is not "correct".

A corollary of Newton's first law is that if a stationary object is subjected to a force, it must be a balanced force. In order to ensure that Newton's laws of motion are also "correct" in the disk's frame of reference, we are forced to "admit" that the force that pushes us outward is "real", and to name it "inertial centrifugal force" or "centrifugal force" for short, according to the direction of the force

With this force, Newton's first law is also completely "correct" in the disk frame of reference.

The reason why we say that this force is not a real force is because no matter what kind of frame of reference we choose, we cannot find the object to which this force is applied.

Hello, it is a pleasure to serve you and give you the following answer: No, centrifugal and centripetal forces are not provided by speed. Centrifugal and centripetal forces are determined by the mass of the object and the distance between them.

When the distance between the objects becomes smaller, the centripetal force increases, while the centrifugal force weakens. The solution to this problem is:1

First, it is necessary to understand the distance between objects, as well as the mass between them. 2.Then, based on the distance and mass between the objects, the centrifugal and centripetal forces between them are calculated.

3.Finally, based on the calculated centrifugal and centripetal forces, the trajectories of motion between the objects are calculated. Personal Tips:

When calculating centrifugal and centripetal forces, special attention should be paid to the distance and mass between objects as they are the key factors that determine the centrifugal and centripetal forces.

Hello, I am very happy to serve you and give you the following answers: Answer: Centrifugal force and centripetal force are not provided by velocity, but by acceleration.

Reasons for the problem:1When an object is in motion, it is subjected to an external force that produces an acceleration that causes the object to produce centrifugal and centripetal forces.

2.Acceleration may occur due to the action of an external force during the movement of the object, which causes the centrifugal and centripetal forces to occur on the object. Workaround and Procedure Steps:

1.First of all, it is necessary to determine the trajectory of the object, that is, to determine the acceleration and velocity of the object. 2.

Then, using Newton's second law, the centrifugal and centripetal forces of an object can be found. Here, the centrifugal and centripetal forces of the object are provided by the acceleration. 3.

When a particle is subjected to an external force, its acceleration a is proportional to the magnitude of the external force f, and the direction is the same as that of the external force f: a = f m, where m is the mass of the particle.

Centrifugal force and centripetal force are two opposite forces that are provided by the velocity of the object. For example, when a small ball moves in a circular path, it will be roughly affected by centrifugal and centripetal forces. The centrifugal force pushes the ball outward, while the centripetal force pulls the ball inward so that the ball moves in a circular path.

So, centrifugal and centripetal forces are provided by the velocity of the object.
