Mass

Mass is an inertial properties of any substance. In physics mass is considered as the such kinds of innertial property of a matter or substance that determines other property of substance. Physists consider mass as a scaller number, because it does not mean any direction. Symbolically mass is expressed as m. Everything have a center. It is considered that mass is concentrated in the center of a substance. Just giving an example of mass. A pen, a cricket ball, a pin a small or big sizes stone everything is substance. Each of these substances have mass in view of different scientists. Different theory of physics shows, how mass determines another properties of substances. If 2 gm masses of a stone throw and hit a glass with comparing to 1 gram stone, the glass will hitted by more force when 2 gm stone is thrown. Weight is different from mass. Weight is a force on a substance by earth. It is vector number The addition, multiplication of mass follows the algebric role. Exactly in physics it considered that mass is a theoretical term and an inertial properties of substances.
