Mass is a fundamental physical property of a body. It gives a good approximation of the amount of matter contained in this body, regardless of where it is located.
The unit of mass: kilogram
The mass is represented by the symbol m, and in the international system its unit is the kilogram (kg).
There are two types of mass:
the inertial mass, which indicates the resistance that a body opposes to a change in its motion under the action of a force
the gravitational mass, which refers to the gravity to which the body is subjected
In practice, these two quantities are equivalent. The experiment showed that they are exactly the same except for 10-12.
Between 1889 and 2019, the kilogram was defined as the mass of the thousand-gram standard of platinum-iridium. However, questions of the accuracy and stability of the standard prompted scientists to turn to the Planck constant.
