What exactly is the quality of physics? Definition of mass in physics

The reason you (and not us) usually mention that the mass is gravity is that we live in an environment with approximately uniform gravitational acceleration. I believe that the junior high school teacher has done a conceptual analysis for you, don't be involved with others. Inertial Mass in Low-Speed Physics:

A broad extension that is inversely proportional to acceleration under the action of the same force. Gravitational mass in Newton's gravitational force: The charge that produces the gravitational force.

In general relativity, it is the dynamic tensor, not the mass, that bends space-time). Inertial mass in high-speed physics: Lorentz invariants of momentum, Ca operators of Poincaré groups.

1.Inertial mass, or how difficult it is to change its state of motion, how difficult it is to produce acceleration under the action of a certain force.

2.Gravitational mass, the ability of an object to participate in gravitational force. Logically, the two don't have to have any connection, but in reality, the two are always in the same proportion, and the gravitational acceleration of a piece of manure is the same as a piece of **.

It shows that the two qualities are in equal proportion, and have nothing to do with the quality of the material. This is the case with small objects, and the same is true for large objects. Suppose that the ratio of the two masses of the materials constituting the celestial body is not uniform, then its inertial centroid and the gravitational centroid may not coincide, such a celestial body is in orbit, the centrifugal force is manifested in the inertial centroid, and the gravitational force is manifested in the gravitational centroid, which will produce a moment, and its rotation behavior will be obvious.

Looking at the universe, the two masses are in the same proportion, which indicates that the two masses are the same problem, which is the so-called equivalent effect principle, which is the basis of general relativity. The theory of relativity says that the gravitational field bends space-time, tilting the time axis towards the axis of velocity, and experiencing time in the gravitational field is the same as moving on the axis of velocity --- doing acceleration, so the magnitude of the gravitational force is perceived, just like the acceleration of the object, which is proportional to the inertial mass. At this point, there is only one mass--- inertial mass.

The gravitational mass and inertial mass are the same. That is, the acceleration of electromagnetic action is the same as the acceleration of gravitational action. Traditional gravitational measurement is either acceleration measurement, or balance (electromagnetic measurement), or spring scale (electromagnetic measurement), in short, there are two categories, one is to use gravity itself to measure the proportional relationship of different objects under the action of gravity, and the other is to use electromagnetic action to indirectly measure the proportional relationship, the previous is to say that different objects have a fixed acceleration ratio under the action of different gravitational fields.

The latter only shows that the electromagnetic field and the gravitational field have the same acceleration effect, and the gravitational field and the electromagnetic field can cancel each other, which is the process of imparting mass to the charge. This mass is actually the inertial mass, which is inseparable from the gravitational mass, why is it inseparable, but it is the proportion of the acceleration of the charge in the gravitational field, where is the gravitational mass? <>

Mass is a mechanical property that can induce the cosmic film to act with a force field in the four-dimensional direction**. There are mass particles that cause inertial forces and spatial bending forces, and everyday mass particles also cause three basic force properties, but some particles do not coexist with the three force properties, such as dark matter.

The properties that the bose particles give to it
