... Electric forces can sometime be used to solve problems with Newton’s laws. But it is not usually possible to use constant acceleration kinematics as the field and force usually vary with distance. One exception is with charged plates which create constant fields and constant forces over reasonable d ...

Ginzburg Landau phenomenological Theory
... Plotting Fs − Fn as a function of ψ is easy to see that there are two possible curves, depending on the sign of the parameter a(T), as shown in Fig. In the case a(T) > 0, the curve has one minimum at ψ = 0. On the other hand, for a(T) < 0 there are minima wherever | ψ |2 = −a(T)/2b(T). Landau an ...

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.
