What is the formula for the mass of motion of an object in the theory of relativity and Newton s the

Comrade Newton's classical mechanics mentioned that f=ma can be derived from a=v t and f=mv t

Comrade Albert Einstein was upstairs as M (1 V 2 C 2) (1 2).

1. In Newtonian mechanics, mass is an inherent property of an object, an immutable physical quantity, which does not change with the state of motion, and has no concept of moving mass;

2. In Einstein's theory of relativity, mass is no longer constant, it is related to the state of motion, m=m0 [(1-v 2 c 2) (1 2)], where m0 shows the mass at rest, which is equivalent to the mass in Newtonian mechanics, which is fixed and unchanging, m is the mass of motion, and v is the speed of motion of the object;

3. From the formula, it can be seen that when v is much less than the speed of light c, m=m0, it goes back to Newtonian mechanics, and Newtonian mechanics and relativity are correct in their respective fields.

To be precise, Newton's classical mechanics only talks about the relationship between force and mass and acceleration, and the qualitative relationship between mass and inertia. f=ma;The greater the mass, the greater the inertia.

General relativity, on the other hand, connects energy and mass in perfect secrecy through the principle of relativity. e=mc2

Newton: You know that.

Considering the relativistic effect, the mass should be m (1 v 2 c 2) (1 2),

In fact, the range of applications is different. Newtonian mechanics applies to low-velocity macroscopic motion, whereas relativity applies to high-velocity motion. The two formulas look different, but Einstein actually derived the kinetic energy theorem from the mass-energy equation.

While the physical basis of Newtonian mechanics is unstable, Newton's second and third laws, are based on reality but cannot be explained. Einstein's special theory of relativity is based on two principles, namely the invariance of the speed of light and the absolute invariance of physical properties within the framework of inertia. All subsequent inferences start from these two properties, the theory of relativity is everything that can be deduced, it is solid, but it is also fragile, and if someone can prove that one of the cornerstones of the theory of relativity is wrong, the whole edifice will fall.

<>I think it would look better that way. The Newtonian kinetic energy equation and the relativistic kinetic energy square are programmized, and p is the momentum. When you compare the two, you can see that the most obvious proto-group cause is that as the velocity of the object increases, the relativistic effect of the mass, which leads to the difference in the Newtonian and relativistic kinetic energy formulas, but other than that, they are very close.

But! When an object moves at a speed close to the speed of light, the kinetic energy formula of the theory of relativity goes through one"Phase transitions"。The kinetic energy changes from the quadratic of momentum to the primary of momentum.

It is this change that causes countless stars to be in space**, from which a large number of heavy elements are created and ejected into space. Through these heavy elements, life emerged, economic development developed, and civilization flourished.

Newtonian kinetic energy only works at low velocity, low energy, and here you have to consider the force or velocity in relation to energy. The theory of relativity applies in all cases (except within the Schwarzschild radius), mass and energy are essentially the same, and mass can be expressed in terms of energy, rather than being completely uncorrelated with mass and energy, as Newton believed. One of the important things that the theory of relativity wants to say is that mass and energy are equivalent to each other.

This is the mass-energy equation.

The kinetic energy formula in classical mechanics is actually an approximation of the kinetic energy formula at low velocities in the theory of relativity. The energy of an object moving with its stationary mass relative to the velocity of the experimental coordinate system is its kinetic energy, that is, its energy relative to rest is when we expand the sequence to the first order, so we have so that the kinetic energy formula of classical mechanics is a first-order approximation of the relativistic kinetic energy formula at the time. The difference between them reflects that we are slow creatures and cannot experience the effects of relativity in ordinary life.

But physically, they are essentially the same.

The calculation method is different, the effect is different, the function is different, the theory used is different, the economic development promoted is different, and each of its formulas is seen through the calculation of the sedan car thousands of times, which has brought a lot of convenience to the people of Zhengdong.

Newton is a world-renowned physics chain writer and scientist, he proposed the theory of relativity, and the formula of Newton's theory of relativity has many applications in physics.

The difference between the two is that the scope of application is different, the theory of relativity is applicable to high-speed motion, and Newton's kinetic energy formula is applicable to low-speed macroscopic motion.

The foundation of the building did not, and facts and experiments proved that the confusion of the concepts of time and motion mass and energy led to the stagnation of theoretical physics!

Newton did not believe that the measure of motion could be derived from both velocity and mass of matter, and the first volume studied the motion of an object in free space without resistance, and many of the propositions involved the determination of the state of motion of a stressed object (orbit, velocity, motion time, etc.) by known forces, and the determination of the force experienced by the state of motion of the object. The second volume deals with the motion of objects given by resistance, fluid mechanics, and wave theory. The third volume of the work is entitled "On the Celestial System of the Universe."

From the results of the first volume and astronomical observations, Newton derived the law of universal gravitation, from which he studied the shape of the earth, explained the tides of the oceans, the motion of the moon, and determined the orbits of comets. The "Rules for the Study of Philosophy" and the "General Interpretations" in this volume have had a great influence on philosophy and theology. "The Mathematical Principles of Natural Philosophy" Whether from the perspective of the history of science or the entire history of human civilization, Newton's "The Mathematical Principles of Natural Philosophy" is an epoch-making masterpiece.

In the history of science, "The Mathematical Principles of Natural Philosophy" is the first classic work of classical mechanics, and it is also the first complete scientific cosmology and scientific theory system mastered by mankind, and its influence covers all fields of classical natural science, and it has repeatedly achieved fruitful results in the following 300 years. From the perspective of scientific research, "The Mathematical Principles of Natural Philosophy" demonstrates a model of a modern scientific theoretical system, including the theoretical structure, research methods, grinding and inquisitive attitude, how to deal with the relationship between man and nature, and other aspects. In addition, the Principia Mathematica of Natural Philosophy and its author's interaction with prominent contemporaries is also a perennial topic in the study of the history of science and other academic history studies.

The relationship between the theory of relativity and Newtonian mechanics is both negative and developing

Newtonian mechanics is based on an absolute view of space-time and cannot explain some phenomena of motion close to the speed of light. The theory of relativity negates the absolute view of space-time in classical mechanics and holds that space-time can be transformed, so it is a subversion of Newtonian mechanics from the foundation.

On the other hand, Newtonian mechanics is a general law of low-speed motion, which is a special case under the relativity system, and the emergence of relativity supplements the physical laws in the field of high-speed motion, which is an inheritance and supplement to Newtonian mechanics, and is the result of the inheritance and development of Newtonian mechanics.

It is the relationship between ordinary mechanics and celestial mechanics.

It is the development of traditional mechanics.

In particular, the special theory of relativity has revolutionized mankind's understanding of space, time and the movement of matter, marking the arrival of a new era in physics.

The biggest difference between relativity and mechanics is about the view of space-time, Newton believed that space is absolute, and that space and time are all consistent. With the advent of the theory of relativity, it changed everyone's concept of time and space.

The theory of relativity in a broad sense refers to the discourse of the concept of relativity, the most common of which are big-small, many-few, more with respect to 1,10 and less with respect to 100,10. The theory of relativity is commonly referred to as Einstein's theory of relativity.

The theory of relativity is all about the problem being discussed by a specific person from a specific angle, and the comprehensive discussion of the problem, no matter who it is, will agree that the objective discussion is the law of science, so there is no relativity theory in science.

Einstein's theory of relativity was originally used to explain what happens when the speed of motion is close to the measured speed. Because the velocity is relative, so all kinds of measured velocities are relatively close, so the theory of relativity should have a wider range of use.

Einstein's theory of relativity was discovered to explain the reason why particles moving at high speeds close to the speed of light do not conform to Newton's laws, but to Lorentz's laws.

For this reason, he made two assumptions: that the laws of motion in different frames of reference have the same mathematical form; The speed of light is the same in different frames of reference.

Special relativity says that there is a relativistic effect in an inertial frame.

Einstein's calculations deduced the results of slow clocks, shrinkage of rulers, and curvature of space, which are different from the traditional definitions.

But today, we find that the particle theory of light is not as solid as in Einstein's time, many phenomena can be explained by the law of waves, Einstein's hypothesis does not have universal laws, according to the current discovery, there can be a more adaptable theory of relativity and compatible with all theories, and its derivation only needs to make a little correction to the original theory of relativity, and does not need to make derivation assumptions.

When the bell moves away at close to the speed of sound, the bell heard is slower than the local bell because it takes time for sound to travel, and when the bell moves away at close to the speed of light, the bell seen is slower than the local bell because it takes time for light to travel, which is the essence of the bell slowness effect calculated by Einstein.

Light is a pure wave, and the relativistic effect is simply a measurement effect, an effect introduced due to the measurement of velocity. Einstein's theory of relativity is a theory of relativity that needs to be revised.

When Einstein deduced the theory of relativity, he did not rule out this effect at all, and there was a huge loophole in his derivation! Therefore, Einstein's theory is a theory that needs to be revised.

Einstein did not challenge classical mechanics, and the theory of relativity needs to be understood in classical mechanics. Too many people don't understand the theory of relativity.

Newtonian classical mechanics has a certain relationship with the theory of relativity, and the relationship between the theory of relativity and classical mechanics is innovative development.

Classical mechanics cannot explain the physical phenomena of high-speed motion and microscopic physical phenomena, while the theory of relativity can explain high-speed physical phenomena more reasonably, and quantum physics can explain microscopic physical phenomena very well.

The basic laws of classical mechanics are Newton's laws of motion or other mechanical principles related to Newton's laws and equivalent, which are mechanics before the 20th century, with two basic assumptions: one is to assume that time and space are absolute, that the measurement of length and time intervals is independent of the motion of the observer, and that the transmission of interactions between matter is instantaneous; The second is that all observable physical quantities can be determined with infinite precision in principle.

Relative mechanics is more perfect than classical mechanics, and it should be said that it has a lot to do with it, and Einstein is a further refinement of Newton.

A long time has passed since the establishment of the special and general theories of relativity, which have withstood the test of practice and history, and are universally recognized truths. The theory of relativity has had a tremendous impact on the development of modern physics and the development of modern human thought. The theory of relativity unifies classical physics logically and makes classical physics a perfect scientific system.

On the basis of the principle of special relativity, the special theory of relativity unifies the two systems of Newtonian mechanics and Maxwell's electrodynamics, and points out that they both obey the principle of special relativity and are covariant to the Lorentz transform, and Newtonian mechanics is just a good approximation of the law of objects moving at low speeds. On the basis of the generalized covariance, the general theory of relativity establishes the relationship between the local inertia length and the universal reference coefficient through the equivalence principle, obtains the generalized covariant form of all physical laws, and establishes the gravitational theory of the generalized covariance, while Newton's gravitational theory is only its first-order approximation. This fundamentally solves the problem that physics was limited to the coefficient of inertia in the past, and it is logically and rationally arranged.

The theory of relativity rigorously examines the basic concepts of physics, such as time, space, matter, and motion, and gives a scientific and systematic view of space-time and matter, so that physics becomes a perfect scientific system logically. The special theory of relativity gives the law of motion of an object at high speed, suggests that mass and energy are comparable, and gives the mass-energy relation. These two results are not obvious for low-speed moving macroscopic objects, but they show extreme importance in the study of microscopic particles.

Because the speed of microscopic particles is generally relatively fast, some close to or even reaching the speed of light, the physics of particles is inseparable from the theory of relativity. The mass-energy relationship not only creates the necessary conditions for the establishment and development of quantum theory, but also provides a basis for the development and application of nuclear physics. The general theory of relativity establishes a well-developed theory of gravitation, which mainly deals with celestial bodies.

Up to now, relativistic cosmology has been further developed, and gravitational wave physics, compact astrophysics, and black hole physics, which belong to the sub-disciplines of relativistic astrophysics, have made some progress, attracting many scientists to conduct research. A French physicist once said of Albert Einstein: "Among the physicists of our time, Albert Einstein will be at the forefront."

He is, and will be, one of the most brilliant stars in the universe of mankind", and "in my opinion, he may be greater than Newton, because his contribution to science has penetrated more deeply into the structure of the basic essentials of human thought." ”
