This computer has many advantages. Its only drawback is its large mass. Its power supply unit has a mass connected to the body. Is the same "mass" referred to in all cases?

Step 1
The first of the meanings of the term "mass" is a measure of the inertia of a physical body. This value is associated with speed, energy, acceleration. So, for example, if the mass is multiplied by the square of the speed and the result is divided by two, the value of the kinetic energy of the body will be obtained. If you multiply it by acceleration, you get a force. An object that has a significant mass is said to be massive.
Step 2
Chemists also use the concept of mass. They use, in particular, such quantities as atomic mass - the mass of one atom, molar mass - the mass of one mole of a substance.
Step 3
In SI, mass is measured in kilograms (kg). It should not be confused with another similar physical quantity - weight. Weight is obtained by multiplying mass by the acceleration of gravity. Therefore, the same body always has the same mass, however, if you move it from the Earth to the Moon, its weight will change. In the SI system, weight is expressed, like force, in newtons (n), but sometimes it is expressed in more convenient units - kilogram-forces (kgf).
Step 4
In a figurative sense, a mass is called a set of something. Apparently, this is due to the fact that even light objects, when there are many of them, have a significant total mass. Mass (plural) refers to the population. A product designed for buyers with small and medium incomes is called mass.
Step 5
Also, a mass is called a substance that is in an aggregate state, which is not yet solid, but no longer liquid. Curd mass is a tasty dish, but it is not as harmless as it seems, since it is much fatter than ordinary curd. In most cases, such a substance is rather homogeneous, nondescript, in connection with which a person who does not want to stand out, to be bright is said to have merged with a gray mass.
Step 6
In electrical engineering and electronics, mass is synonymous with common wire. In devices that do not use printed wiring, a massive chassis is often used as a common wire, and therefore this term was coined.
