... time. For such a general motion, calculate ~v and ~a. If one defines, ~v = vr r̂ + vθ θ̂ + vφ φ̂ and ~a = ar r̂ + aθ θ̂ + aφ φ̂, (a) Express vr,θ,φ and ar,θ,φ in terms of r, θ, φ and their derivatives. (b) Express the kinetic energy of the particle in terms of these variables. (c) Consider a particl ...

So, the coupling constants “run”, i.e. change with energy. o We expect that if the four forces are unified, the running coupling constants will converge at some high energy.
