... atomic momentum is (5f!) = (tikL - tiks) = tikL ; the mean contribution of tifs is zero because spontaneous emission occurs with the same probability in two opposite directions. The mean radiative force is then simply nfL times the rate of absorption-spontaneous emission cycles. This rate, on the or ...

... Example: Since the current changes direction relative to the magnetic field as you go around the loop, the magnetic field will exert force of equal magnitude but opposite direction on opposite sides of the loop. These forces all cancel out resulting in zero net force. However, since this force is up ...

Time in physics
Time in physics is defined by its measurement: time is what a clock reads. In classical, non-relativistic physics it is a scalar quantity and, like length, mass, and charge, is usually described as a fundamental quantity. Time can be combined mathematically with other physical quantities to derive other concepts such as motion, kinetic energy and time-dependent fields. Timekeeping is a complex of technological and scientific issues, and part of the foundation of recordkeeping.
