According to the general theory of relativity, accelerating mass produces gravitational waves, for e

For example, if you take a stick and wave it, it theoretically produces gravitational waves, but it's not too weak. It is really possible to generate detectable gravitational waves from neutron stars or black holes that rotate at high speed with each other, and when two black holes merge, **!

Mass produces space-time bending, imagine a heavy object on the rubber film, the mass of the object is like a heavy object rolling on the rubber film, and the vibration of the rubber film caused by it corresponds to gravitational waves.

Gravity is considered one of the fundamental forces in the universe in classical physics, directly proportional to mass and inversely proportional to distance. But in Einstein's theory, gravity is no longer a fundamental force, but only a manifestation of the bending of the structure of space-time. The reason for the bending of the structure of space-time is the huge mass.

The planets in the solar system orbit the sun, which is explained in classical physics because the planets are driven by the sun's gravitational pull and orbit the sun.

Liu Wuqing's speech topic: gravitational wave communication methods and devices.

Binary star systems radiate gravitational waves and lose energy and move closer to each other.

Protons moving at low velocity and incoming particles, if they have the same De Broglie wavelength, then the ratio of their momentum to du is.

zhi1:1, the ratio of kinetic energy is 4:1.

Solution: DAO is composed of p=h, both are the same, so the ratio of their momentum is 1:1.

By the classical relation, kinetic energy e=p 2m, so the ratio of their kinetic energy is 4:1.

Momentum is a conserved quantity, which is expressed as the constant sum of momentum within a closed system (not subject to external forces or the sum of external force vectors is 0).

Kinetic energy is a scalar quantity, no direction, only magnitude, and cannot be less than zero, consistent with work, and can be directly added or subtracted.

Alpha particles have two protons, two neutrons. Combined with de Broglie's formula, calculate the ratio of momentum, because of the low velocity, there is no need to consider the relativistic effect, so.

There is a theoretical possibility, but no one has observed or confirmed such a fact in natural reality so far, and as for quantum entanglement, it is not a motion phenomenon in which matter or objects are displaced, but a phenomenon of synchronous and coordinated entanglement between two anti-identical objects.

Mass and energy are two different descriptions of the same nature, there is a simple proportional relationship between them, that is, e=mc 2, and the velocity increases, in other words, the kinetic energy increases, the energy of the object increases, and the corresponding mass increases, the faster the velocity moves, the more obvious the relativistic effect, and the classical mechanics that is usually in contact with ignores the theory of relativity, so it does not involve the problem of mass increase.

The energy acting on a system has two effects, on the one hand, for an increase in velocity and on the other hand, an increase in mass. And with the increase of speed, the latter trend becomes more obvious. In fact, momentum is a component of energy.

And the product of mass and velocity is momentum. In fact, it should be that mass and energy were positively correlated. Because it is impossible for an object to move faster than the speed of light!

I suggest you ask Albert Einstein, I promise he will!

In the same frame of reference, the momentum of the particle is determined.

There is no such thing as relativistic momentum or classical momentum.

The landlord mistakenly thinks that the velocity of the rest mass is the classic momentum.

And in fact, this classical momentum has no meaning, it is not the momentum of a particle at all.

m=mo [(1-v 2 c 2) (1 2)]=2mo solution v=(3 4) (1 2)c, this is the answer you want.

I really hope that the current physics teachers can be more rigorous in their questions, because such questions will mislead students to misunderstand the principles of physics.

First of all, the formula is this m=mo [(1-v 2 c 2) (1 2)] when the velocity is 0 classical momentum mo=m

When m=2mo, the condition is satisfied.

1/(1-v^2/c^2)^(1/2)=21-v^2/c^2)^(1/2)=1/2

1-v^2/c^2=1/4

v^2/c^2=3/4

v^2=3c^2/4

v=3^(1/2)c/2

That is, (3)*c 2 is the root number 3 of the 2nd of the speed of light.

c is the speed of light, v is the velocity, and mo is the mass at rest.

The relativistic momentum of the particle is p=m0v [(1-v2 c2) and the non-relativistic momentum is p0=m0v, where m0 is the static mass of the particle and v is the velocity of the particle.

Let p=2p0, bring in the two momentum expressions, get m0v [(1-v 2 c 2), simplify (1-v 2 c 2), square the two sides of the equation, and solve v= 3 2 c, that is, the particle velocity is about 3 2 c when its momentum is twice the non-relativistic momentum.

Relativistic momentum p = mv = m0 * v sqrt(1-v2 c2).

where sqrt stands for open-squared operation.

Non-relativistic momentum p'=m0*v

p=2p'm0*v /sqrt(1-v^2/c^2) =2*m0*vsqrt (1-v^2/c^2) =1/21-v^2/c^2 = 1/4

v^2/c^2 = 3/4

v = 3/2) c =

c stands for the speed of light.

That is, when the velocity of the object reaches the speed of light, the relativistic momentum is twice that of the non-relativistic momentum.

The velocity when the kinetic energy is twice the rest energy should be (8 9) 2 with the formula e=mc 2-m0c 2=2m0c 2 to find m=3m0 and then use m=m0 (1-v 2 c 2).

Kinetic energy = total energy - energy at rest = > total energy = 2 * energy at rest.

Total Energy = *Resting Energy = > 2

1/sqrt(1-ββsqrt(

Momentum = Velocity * Kinetic Mass = cm0 = 2 * sqrt(

First, general relativity doesn't actually describe gravity. The general theory of relativity describes the spatial density gradient. Newton's theory of gravitation describes and accurately ** gravitation.

The theory of general relativity describes the deformation of space around an object made up of neutrons. Half of the mass of stars and planets is determined by the neutron content. Neutrons are the combination of semi-spin electrons and semi-spin protons to produce semi-spin neutrons.

Since neutrons are semi-spin, this means that electrons and protons are not next to each other, but rather they have to flip over to each other; The result is that two particles occupy one unit of space, in other words, the space is compressed.

The assumption in quantum physics that prevents this from happening is that space has no structure of its own. Not only does space have a specific quantum structure, but the quantum structure of space is stretched due to the binding of neutrons. The density of the space closest to the large neutron is less than the density of the space far away from the neutron; General relativity uses the mathematics of Riemannian curvature to map spatial density gradients.

There is a less dense space near a massive object, and a gradient of a denser space in the direction away from the object, the result of which is that the spatial density gradient creates a prism that bends the surrounding light. In addition, the lower spatial density from massive objects (stars) means that planets orbiting in orbit travel shorter distances than planets that are farther away from massive objects.

Newton's laws determine gravitation, but Riemann's curvature math maps together all the forces required by the density gradient in space, not just gravity.

Gravitation is one of the four forces in atoms. So somehow, one atom caused the change of space-time. The amount of change depends on the square of the distance to the atom.

The closest to the atom has the greatest change. This change in space-time acts on other atoms in some way. The closer you are to the atoms, the shorter the distance between anything and at the same time, the rate of change in time slows down.

So it's clear that gravity arises because atoms prefer to be in a shorter distance slower time position.

The concept of space-time is strange, but space and time change together to keep the speed of light constant (one of the fundamental constants in the universe). The change in the rate of time and the distance between things both prove that general relativity is correct. Only the wavelength of photons is elongated or shortened by changes in space-time.

Gravitational force is the distortion of space, which will form a gravitational field, the stronger the gravitational force generated, the slower time will become, and the weaker the gravitational force generated, the faster time will be.

The reason for the occurrence of gravitational force (brief description): When the high-energy particles moving in the universe pass through matter (celestial bodies or particles), part of them are intercepted and absorbed to form a weak energy region (Einstein's space-time curvature), which is the gravitational range mv2=e=mv2 (the formula of the law of conservation of energy conversion). For more details, please see the forthcoming gravitational hypothesis, "Elemental Periods and the Causes of Gravitation".

An object with mass causes the curvature of space-time around it, and this curvature of space-time causes all gravitational effects, i.e., gravity originates from the curvature of space-time caused by mass.

Gravitational force is generated, determined and controlled by energy, the greater the energy of the object, the greater the gravitational force, and the gravitational force of the object is proportional to the energy.

For example, if we throw something upwards and then it falls to the ground naturally, the phenomenon of the object falling naturally to the ground is called gravity.
