Detailed explanation-1: -Mass (M) is the measure of the amount of matter in an object. Mass is measured in grams (g). Mass is measured on a balance by comparing the object against other objects with known masses. These objects are called balance weights.
Detailed explanation-2: -Mass is the measure of matter in a particular object. No matter where that object is in the vast universe, it will have the same mass. Weight, on the other hand, is a measure of how much gravitational force is exerted on an object.
Detailed explanation-3: -In common usage, the mass of an object is often referred to as its weight, though these are in fact different concepts and quantities. Nevertheless, one object will always weigh more than another with less mass if both are subject to the same gravity (i.e. the same gravitational field strength).
Detailed explanation-4: -The mass of a body is the measurement of the amount of matter in it. The SI unit of mass is the kilogram (kg). The mass of a body remains constant at all times.
