Mechanics

Motion is everywhere from the motion of an elephant to the motion of the fastest aircraft. The study of motion is called Mechanics considering the motion of bodies that are large enough relative to the subatomic realm and the speed is considerably less than the speed of light.

The study of motion without considering the cause of motion is a part of Mechanics called Kinematics. The study of motion considering the cause of motion, that is force is another part of Mechanics called Dynamics. Mechanics is the study of motion in relationship with the force and matter.

Here we deal with the mechanics in Physics also called classical mechanics or Newtonian mechanics. The rules and theories or principles in classical mechanics are vital in all realms of Physics.
