Branches of mechanics:
Mechanics is basically divided in to two parts Static's and Dynamics, Dynamics is further divided in kinematics and kinetics
Statics: It deals with study of behavior of body at rest under the action of various forces, that are in equilibrium.
Dynamics: Dynamics is study of object in motion
Kinematics: It deals with motion of body without considering the forces acting on it.
Kinetics: It deals with motion of the body considering the forces acting on it.
