What is mechanics? Give definitions of its sub-branches.
(N/A) Mechanics: The branch of physics which studies and deals with the motion of objects is called mechanics. It is broadly divided into two sub-branches:
$(1)$ Kinematics: The branch of mechanics that describes the motion of objects without considering the causes of that motion (i.e.,forces) is known as kinematics.
$(2)$ Dynamics: The branch of mechanics that describes the motion of objects by considering the causes of that motion (i.e.,forces) is known as dynamics.
