mass

     

Mass is a funamental concept in physics, roughly corresponding to the intuitive idea of how much matter there is in an object. Mass is a central concept of classical mechanics and related subjects, and there are several definitions of mass within the framework of relativistic kinematics (see mass in special relativity and mass in General Relativity). In the theory of relativity, the quantity invariant mass, which in concept is close to the classical idea of mass, does not vary between single observers in different reference frames.

Trivia about mass

  • Technically, the measure of a body's inertia is known as this property of matter
  • In 1998 it was in the news that particles called neutrinos do have this -- perhaps a millionth of an electron's
