History of inertia, examples of inertia and explanations

Matter is in motion, and physics has a lot of discussions about inertial frames. Galileo discussed. Einstein was especially discussed.

The transformation of the inertial frame is not only a change in the velocity data, but also involves the applicability of the laws of physics. No one has raised the question of the inconsistency of the laws of physics in different inertial frames.

The Galilean transformation is a linear transformation, which is a linear transformation of velocity. It's just a difference in the observer's perception of time and space. The substantial effect of inertia on physical properties is not taken into account.

Einstein discussed inertial frame transformations and used the Lorentz transform. Since the Lorentz transform is wrong. Hence the physical absurdity of the false space-time distortion.

Does the inertial frame have an effect on the motion of an object, and does it affect the applicability of the laws of physics?

Since velocity is associated with the kinetic energy of an object, kinetic energy is unique to each object. The speed of transformation inevitably leads to inconsistencies in our understanding of physical phenomena, i.e., the same motion phenomenon is observed in different inertial frames, and the same motion formula cannot be used.

When the onlookers calculate the value of the motion, they come to different conclusions. The Galilean transformation is not just a matter of frame of reference, it is a distortion and deviation from the real physical condition of the object. This transformation cannot be equivalent and is therefore inappropriate.

Inertia leads us to arrive at the laws of physics that contain false information and are therefore imprecise.

The data obtained by the inertial frame transformation is also double-blind. The amount of superposition has not been scientifically determined. Therefore, the real data of the inertial frame is not carefully determined.

Only by excluding the influence of the observer can the only true physical relationship be obtained. Our existing laws of physics are influenced by inertia, resulting in a disability branded with false information.

Law. It is an empirical formula, how can you talk big and boast of laws. Only by eliminating this influence can the true laws of physics be obtained.

Explanation of inertia.

inertia]

A property of the substance, unless it is subjected to some external force, the substance will remain stationary or move at a uniform speed in the same straight line, and any change in motion is measured by the acceleration of the center of mass Inertia brings the train to the station Explained in detail (1).Physics noun . It refers to the nature of an object that retains its original state of motion or rest.

1. The property of an object that remains at rest or in a state of uniform linear motion is called inertia. Inertia is an intrinsic property of an object, which is manifested as a degree of resistance of an object to a change in its state of motion, and mass is a measure of the magnitude of an object's inertia.

2. When the external force acting on the object is zero, the inertia is manifested as the object keeping its motion state unchanged, that is, maintaining a stationary or uniform linear motion; When the external force acting on the object is not zero, inertia is expressed as the degree of difficulty with which the external force changes the state of motion of the object.

3. Under the action of the same external force, the object with smaller acceleration has a larger mass and greater inertia, and the object with greater acceleration has a smaller mass and less inertia. Therefore, the inertia of an object will not change at any time (with or without external force) or under any emotion (rest or motion), let alone disappear. Inertia is a property of matter itself.

The term inertia was first explicitly put forward by Galileo in "Dialogues on the Two World Systems of Ptolemy and Copernicus", which probably means that an object has an inherent property that makes it maintain its original state of motion (i.e., velocity vector).

The image point is understood as an object that has the property of maintaining its original velocity, unless an external force forces it to change

For example, if you are in a car, the car is driving at a constant speed, you are used to the speed at which the car is moving forward, and suddenly the car brakes suddenly, but you are still moving at the original speed, so people will lean forward, similar examples: bombs dropped from airplanes, long jumps, shot put, in fact, objects have inertia everywhere in life.

In addition, let's explain the relationship between mass and inertia.

In Galileo's time, there was no clear concept of mass, and the definition of mass was explicitly proposed in Francis Bacon's "New Tools", where he defined mass as "the amount of matter contained in an object", which is now defined in junior high school textbooks as "the amount of matter contained in an object".

Later, when Newton proposed the first law of motion, he really combined mass with inertia, that is, mass is a measure of the magnitude of inertia, so it should be said that mass is related to inertia, not the other way around (but because the current textbook first introduces mass, it is said that the magnitude of inertia is determined by mass, which is also beyond reproach).

However, this is only inertial mass, and when Newton studied gravitational force, he did not use inertial mass, but defined it differently: gravitational mass, and in this sense, mass is the property that makes objects attract each other.

Later, through a series of theories, it was proved that the inertial mass is equal to the gravitational mass, which was proved in "Mechanics" (2nd edition, Qi Anshen, Du Chanying, Higher Education Press).

Inertia is an intrinsic property of all objects, whether solid, liquid, or gas, whether the object is in motion or at rest. Everything has inertia. We call the property of an object that remains in constant motion inertia.

Inertia represents how easy it is for an object to change its state of motion. The magnitude of inertia is only related to the mass of the object. It is relatively difficult to change the motion state of an object with a large mass, that is, it has a large inertia; The motion state of an object with a small mass is relatively easy to change, that is, the inertia is small.

When the car starts or accelerates, due to inertia, the person maintains a constant state of stationary or original speed, and moves backwards relative to the car, so it leans back; When braking in an emergency or stopping suddenly, the person maintains the original speed due to inertia and moves forward relative to the car.

For example, when a person is riding in a car, when the emergency brake is made, the person will fall forward, explaining: the person stands on the car and is carried forward by the car. When the car brakes, the car comes to a stop quickly. The person's feet are also stopped by the friction of the bottom plate, but the upper body is still "running" forward due to the action of inertia, so the person has to fall forward.

People and cars move forward together. When the car suddenly stops due to braking, the person will continue to move forward because of inertia, so the person will lean forward.

You can splash water and use inertia.

When the car is driving at a constant speed, people and the car do a uniform linear motion together, and when the car accelerates suddenly, the lower body of the person accelerates with the car to accelerate the linear motion, due to inertia, the upper body of the person still has to maintain the original speed, so at this time the person will fall backwards (leaning back). When the car starts, it accelerates, and the principle is the same as above.

When the car brakes suddenly, that is, the car does deceleration linear motion, the lower body of the person and the car do deceleration linear motion together, and due to inertia, the upper body of the person still has to maintain the original rapid motion state, so at this time the person will fall forward.

Because energy does not disappear out of thin air, nor does it arise out of thin air, but only transforms from one form to another, or from one object to another. Inertia, on the other hand, is the phenomenon that occurs during the conversion or transfer of energy (at or after the inflection point).

For example, swings, pendulums of mechanical clocks, and other swings are all phenomena of inertia that transform or transfer energy;

For example, if a falling object falls from a high altitude, if it hits a pit on the ground, it is inertia that transfers the potential energy to another object and produces deformation; If it jumps like a ball, it is the kinetic energy that is transformed and raised;

For example, when the car accelerates or brakes, the mechanical energy of the car, in addition to being transferred to the car to produce kinetic energy, is also partially transferred to people to produce kinetic energy. It's just that the mechanical energy transferred by the car sometimes exceeds the energy that people can bear, so people have to lean forward and back shells, that is, inertia.
