Mechanics

Mechanics is the branch of physics which concerned with the behavior of physical bodies when subject to force or displacement, and the subsequent effects of bodies on their environment. It involves [Basically mechanics involves the study of force, vector, motion momentum, energy and the dynamic of object.] the study of moving object. Mechanics is the study of the way matter and forces interact with each other. Here we are concerned with rigid macroscopic bodies. These are bodies that you can easily see, do not bend, and are in the solid state.

Mechanics has several branches. Some of them are statics, dynamics, and kinematics.

• Statics:It concerns itself with forces when no change in momentum occurs.
• Dynamics:It is concerned with forces and matter when a change in momentum does occur.
• Kinematics:It is a study of motion without regard to the forces present. It is simply a mathematical way to describe motion.

There are two basic types of motion one is linear motion (the motion of  an object or a particle along a straight line) and the other is circular motion(the motion of an object or a particle along the circumference of a circle)

To know about mechanics, we have to know about mechanical bodies because basically relates to the motion of the body and motion of the body depends upon the various things one of them is nature of the body.

• Particles: these are the bodies with a little internal structure, treated as mathematical points in a classical mechanics.
• Rigid body: It has a specific shape and size, but retain a simplicity close to that of particle, adding just a few so called degree of freedom, such as orientation in a space.
• Semi rigid body: These are elastic bodies.
• Non rigid body: These are the fluids and gases.
