A basic theoretical concept of mass in physics. Mass is a basic property of an object that measures the impedance of the acceleration created on the object by the application of force. Newtonian mechanics relates the force and acceleration of a mass of matter. The practical concept of mass is the weight of the object. So, the total amount of matter is called mass.
The mass of the object never changes. But the weight of the same object may be different due to positional reasons because the weight is the result of gravity. So even if the mass of the object is variable, its weight will be different in the center of the earth, on the surface of the earth, and in space.
Mass is a physical quantity that does not change with the change of position of the object above the surface of the earth. An astronaut with a mass of 75 kg will have a mass of 75 kg on the moon or in the orbit of the earth or the moon. No matter how much space the astronaut is made of, its mass remains unchanged everywhere.
The mass level is [M]
Unit of Mass: :
The unit of mass in the international system is the kilogram (kg), and the unit of mass in the C.G.S method is the gram (g), and the unit of mass in the British system is the pound.
Characteristic of Mass:
The mass characteristic depends on an object. The mass does not change even if an object is taken to the earth or anywhere in the universe. Moreover, the mass of an object does not depend
on anything, such as motion, temperature, magnetism, electric current, etc. So it is said that mass is the feature of the object.
