MASS

                      Mass is a property of a physical object that quantifies the amount of matter and energy it is equivalent to. Unlike weight, the mass of something at rest stays the same regardless of location. Mass is a central concept of classical mechanics and related subjects.

 

                      In physics, mass  is a property of a physical body which determines the body's resistance to being accelerated by a force and the strength of its mutual gravitational attraction with other bodies. The SI unit of mass is the kilogram (kg). As mass is difficult to measure directly, usually balances or scales are used to measure the weight of an object, and the weight is used to calculate the object's mass.

                                              SI Unit of mass is Kilogram.

                                                     Unit of mass is "m".
