What's the difference between Mechanics, Dynamics and Kinematics?

Mechanics, Dynamics and Kinematics?
Just wondering, been asking myself this for a while, so I thought I'd post it.
Thx for any replies already.

Mechanics,classical mechanics that is,comprises 3 big subtheories:
1.Statiscs.Describes the properties of bodies that do not interact.E.g.it calculates mass center coordinates,inertia moments,volumes,surfaces of bodies.Its notions are:mass,volume,mass density,moment of inertia...
2.Kinematics.In general kinematics studies movement.Its notions include "coordinate","velocity","speed","acceleration","momentum","kinetic energy","angular momentum"...
3.Dynamics means evolution under the influence of forces.The key-word is 'force' and notions which include "force":torque,potential (enertgy),work,(mechanical) power...
