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

Examples
1) Athlete seen in the photo reached up to the speed of
44.72 km/h when he broke the world record in 2009,
Berlin, GERMANY. Calculate his speed in terms of m/s.
2) One of the heaviest cars in the world is Maybach 62 and it weighs
28 kN. Calculate its mass in terms of kg.
6.2 m long, 5513 cc, 543 hp 28 kN
