This description of the possible stationary states of the bound particle in the random force field is taken as a starting point for establishing a diffusion equation in configuration space. Since we identify the first component with the drift velocity, we show that it must be the solution to a...
The resulting relativistically covariant equation of motion is expressed in terms of standard optical parameters. Explicit expressions for secular changes of osculating orbital elements are derived in detail for the special case of the Poynting-Robertson effect. Two subcases are considered: (i) central...
The equation of motion is x=3t+5, y=1/2t2+3t-4(SI)(1) The position vectors at time t = 1s and time t = 2s are obtained, and the position shifts of these prime points in 1 second are calculated; (2) Calculate the mass velocity and calculate the mass velocity when t = 4 s;...
Equation of motion (EOM): ddt∂L∂r˙=∂L∂r yields the Lorentz force: ∂L∂r=e∇ϕ−e∇(v⋅A)=e∇ϕ−ev×(∇×A)−e(v⋅∇)A ddt∂L∂r˙=ddt(mv−eA)=mv˙−e(r˙⋅∇)A−e∂tA ...
In Chapter 1 we have seen that the equation characterizing the diffusion of suspended particles contains terms l /蟿, l 2 /2蟿 referring to the motion of a particle. We shall now investigate how these values can be related to the state of motion of the liquid in which the particles are...

摘要: The most general form of the equation of motion of a charged particle is derived. The equation allows for an arbitrary self-field and is consistent with energy-momentum conservation, angular momentum conservation and the Dirac mass renormalization....
