Mass , in physics, quantitative measure of inertia, a fundamental property of all matter. It is, in effect, the resistance that a body of matter offers to a change in its speed or position upon the application of a force. Mass is measured in units of kilograms. What is Mass ? Mass , in physics, is defined as the measure of the amount of matter present in an object or a system. Mass is an intrinsic characteristic of an object and is independent of its location or the forces acting upon it. The standard unit of mass in the International System of Units (SI) is the kilogram (kg). Mass is the amount of matter in an object or a measure of its inertia. Learn how mass differs from weight, how to measure mass , and how mass relates to scientific laws and phenomena. Learn what mass is , how to measure it, and how it differs from weight. Find out the formula for mass , the units of mass , and the types of mass in physics.
