  • Atomic units [r]: A system of units convenient for atomic and molecular calculations. [e]
  • Centrifugal force [r]: A radially outward force experienced by an object moving in a curved path [e]
  • Centripetal force [r]: The force directed normal to the path of a moving body that enables the body to navigate the curvature of the path [e]
  • Clairaut's theorem [r]: A theorem describing the figure of the Earth as an oblate spheroid. [e]
  • Comité International des Poids et Mesures [r]: An international committee set up to promote uniformity in units of measurement. [e]
  • Coriolis effect [r]: A disorientation caused by misinterpretation of rotational signals by the ear, important particularly to astronauts and pilots. [e]
  • Coriolis force [r]: An inertial force upon a moving object that is perpendicular to its velocity as that is seen from a rotating frame of reference, and also to the axis of rotation. [e]
  • Current mirror [r]: An electrical circuit designed to control a current through one active device by copying the current in another active device, thereby keeping the output current constant regardless of loading. [e]
  • Doppler effect [r]: Frequency changes of a wave due to relative motion between source and observer. [e]
  • Electronic band structure [r]: The very closely spaced energy levels available to electrons in solids, which are separated from each other by energy gaps. [e]
  • Fermi function [r]: The equilibrium occupancy of an energy level in a system of independent fermions at a fixed temperature. [e]
  • Foucault pendulum [r]: A pendulum demonstrating the Earth's rotation as it maintains its plane of motion independent of movement of its suspension attached to planet Earth. [e]
  • Frame of reference (physics) [r]: An observational set of coordinates tied to the motion of an observer, used to describe physical events and possibly including a measurement apparatus. [e]
  • Gyromagnetic ratio [r]: The constant of proportionality between the magnetic moment and angular momentum of an object. [e]
  • Hybrid-pi model [r]: A circuit model used for analyzing the small-signal behavior of transistors. [e]
  • Inertial forces [r]: Forces introduced to enable the use of the laws of motion in accelerating frames of reference, such as rotational frames [e]
  • Inertial frame of reference [r]: A frame of reference in which the laws of physics take their simplest form. [e]
  • Liénard–Wiechert potentials [r]: Scalar and vector potentials that allow determination of exact solutions of the Maxwell equations for the electric field and magnetic flux density generated at an arbitrary location by an ideal point charge moving in a trajectory prescribed in advance (not calculated from any dynamical model). [e]
  • Magnetic moment [r]: A vector property of an object that determines the torque it experiences in a magnetic flux density. [e]
  • Magnetization [r]: Magnetic moment per unit volume of a material, denoted M, defined in terms of the magnetic moments of its constituents by M=(1/V)Σj mj where the magnetic moment mj of the j-th constituent in the volume V is a vector property that determines the torque the object experiences in a magnetic field tending to align its moment with the field. [e]
  • Measurement in quantum mechanics [r]: The interpretation of measurement in quantum mechanics [e]
  • Metre (unit) [r]: Unit of length; one of the seven SI base units. [e]
  • Miller effect [r]: The increase in the equivalent input capacitance of an inverting voltage amplifier due to a capacitance connected between two gain-related nodes. [e]
