  • Moment of inertia is analogous to mass in discussions of rotational motion.
  • Moment of momentum or angular momentum is the rotational analog of momentum.
  • Magnetic moment is a dipole moment measuring the strength and direction of a magnetic source.
  • Electric dipole moment is a dipole moment measuring the charge difference and direction between two or more charges. For example, the electric dipole moment between a charge of -q and q separated by a distance of d is

Famous quotes containing the word definitions:

    The loosening, for some people, of rigid role definitions for men and women has shown that dads can be great at calming babies—if they take the time and make the effort to learn how.
