What is the difference between “kinematics” and “dynamics”?

Posted on by Nicholas52

I have noticed that authors in the literature sometimes divide characteristics of some phenomenon into "kinematics" and "dynamics".

I first encountered this in Jackson's E&M book, where, in section 7.3 of the third edition, he writes, on the reflection and refraction of waves at a plane interface:

Kinematic properties: (a) Angle of reflection equals angle of incidence (b) Snell's law

Dynamic properties (a) Intensities of reflected and refracted radiation (b) Phase changes and polarization

But this is by no means the only example. A quick Google search reveals "dynamic and kinematic viscosity," "kinematic and dynamic performance," "fully dynamic and kinematic voronoi diagrams," "kinematic and reduced-dynamic precise orbit determination," and many other occurrences of this distinction.
