Mechanics:

Mechanics is the study of the way matter and forces interact with each other. Here we are concerned with rigid macroscopic bodies, that is, bodies which you can see easily, do not bend, and are in solid state.

Statics is a field within mechanics which concerns itself along with the forces when no change in momentum takes place. Dynamics is a field concerned with forces and matter when the change in momentum occurs.

Kinematics is the study of motion without regard to the forces present. It is a mathematical way to describe motion. Mechanics is the branch of physics concerned with the behavior of physical bodies when subjected to forces or displacements, and subsequent effect of bodies on their environment.

The major division of mechanics discipline separates classical mechanics from the quantum mechanics. Classical mechanics has especially been viewed as a model for other so called exact sciences. Classical mechanics is one of the two major sub-fields of study in the science of mechanics, which is concerned with the set of physical laws governing and describing mathematically the motions of bodies and aggregates of bodies geometrically distributed within a certain boundary under the action of a system of forces. The other subfield is the quantum mechanics. Classical mechanics is used for describing the motion of macroscopic objects, from projectiles to parts of machinery, as well as astronomical objects, like spacecraft, planets, stars, moons, and galaxies. Besides this, many related specialties exist which deal with gases, liquids, and solids, and so on. Additionally classical mechanics is enhanced by special relativity for high velocity objects which are approaching the speed of light. General relativity can be employed to handle gravitation at the deeper level, and finally, quantum mechanics handles the wave-particle duality of molecules and atoms.
