mass

/ măs /

1. A measure of the amount of matter contained in or constituting a physical body. In classical mechanics, the mass of an object is related to the force required to accelerate it and hence is related to its inertia , and is essential to Newton's laws of motion . Objects that have mass interact with each other through the force of gravity . In Special Relativity, the observed mass of an object is dependent on its velocity with respect to the observer, with higher velocity entailing higher observed mass. Mass is measured in many different units; in most scientific applications, the SI unit of kilogram is used.
2. See Note at weightSee also rest energy
