... To solve this equation we need to know the field at x but this depends on the orbit equation that we are trying to obtain. . . That’s when our approximation is needed: We use the undisturbed orbit, x = x0 + rL sin ωc t. As before, we expect to have a drift, vE , superimposed to a gyration movement. ...

... ma* = FC + ΣFi + (q²/4m){B  [Br]}. If the applied magnetic field is weak, then the last term is very small (being of the order of B²) and can be neglected. If FC + ΣFi is negligible, then we have ma* = (q²/4m){B  [Br]}. Let’s first look at the direction of this “centrifugal” type term. [Br] has ...

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.
