Non-Rigid Body Mechanics

Fluid Mechanics

Mechanics

Statics (Stationary or constant velocity particles/bodies)

Dynamics (Bodies in accelarated motion)

Kinematics (deals with geometric aspects of motion)

Kinetics (deals with forces causing the motion)

As one of the branches of physical sciences, mechanics is concerned with the state of rest or motion of bodies

subjected to action of forces.

Elasticity Plasticity Mechanics of Materials

Fundamental Definitions in Mechanics

Position: Location of bodies in space.

Time: Duration in motion.

Mass: Resistance of body to action.

Force: Effect of one body on another.
