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. 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. Learn what is mass , how to calculate it, and its unit of measurement. Find out the difference between mass and weight, and see examples and solved problems on mass . Mass is an intrinsic property of a body. It was traditionally believed to be related to the quantity of matter in a body, until the discovery of the atom and particle physics. It was found that different atoms and different elementary particles, theoretically with the same amount of matter, have nonetheless different masses. Mass in modern physics has multiple definitions which are conceptually distinct, but physically equivalent. Mass can be experimentally defined as a measure of the body's ...
