Newton’s laws of Motion
In kinematic, we study only the motion of particles, which consists of “one dimensional motion” and “two dimensional motion”.
In dynamics, the study of the “cause of motion” i.e. “force” is not studied.
In Newton’s laws of motion we study the causes of motion, in which we study Newton’s three laws of motion.
This branch of physics in which we study motion and the cause of motion, is called “dynamics”.
