Moment - Science, Engineering, and Mathematics

Science, Engineering, and Mathematics

• Moment (mathematics), used in probability theory and statistics
• Moment (physics), several related concepts, including:
  • Angular momentum or moment of momentum, the rotational analog of momentum
  • Electric dipole moment, a measurement of the charge difference and direction between two or more charges
  • Magnetic moment, a measure of the strength of a magnetic source
  • Moment of inertia, a measure of an object's resistance to changes in its rotation rate
  • Torque or moment, the tendency of a force to rotate an object about an axis
  • Bending moment, a moment that results in the bending of a structural element
  • First moment of area, a property of an object related to its resistance to shear stress
  • Second moment of area, a property of an object related to its resistance to bending and deflection
  • Polar moment of inertia, a property of an object related to its resistance to torsion
  • Image moments, statistical properties of an image
  • Seismic moment, quantity used to measure the size of an earthquake
