Particle energy.

Since the energy of a free electron is entirely kinetic we can disregard the potential energy term and state that the energy, \(E = \dfrac{1}{2} mv^2\) Using De-Broglie’s particle-wave duality theory we can assume that the electron has wave-like properties and assign the electron a wave number \(k\): \(k=\frac{p}{\hbar}\)

Particle physics is concerned with structure and forcesA heuristic derivation of the Schrödinger equation for a particle of mass \(m\) and momentum \(p\) constrained to move in one dimension begins with the classical equation \[\label{eq:1}\frac{p^2}{2m}+V(x,t)=E,\] where \(p^2/2m\) is the kinetic energy of the mass, \(V(x, t)\) is the potential energy, and \(E\) is the total energy.A further difference between magnetic and electric forces is that magnetic fields do not net work, since the particle motion is circular and therefore ends up in the same place. We express this mathematically as: W = ∮B ⋅ dr = 0 (21.4.5) (21.4.5) W = ∮ B ⋅ d r = 0.
