What is mass?

The quantity of matter in an object is called its mass. We must know that the meaning of mass of a body is different from that of the weight of that body. The two terms, mass and weight, are different in the real sense. But in the initial stages for children, the difference is ignored and we use the terms weight and mass in the same sense. Weight of an object changes from place to place, above and below the surface of the earth, but mass of a body never changes. We know, in the surface of the earth we take the units of mass similar to the units of weight.

Standard unit of Mass or Weight:

The standard unit of mass is kilogram and in short it is written as kg. It is used to measure the mass of heavy objects such as bags of grain, stones, etc. The smaller unit of mass is gram and in short it is written as g. It is used to measure the mass of lighter objects.
