Physics 1 Mechanics Overview. Mechanics is the branch of Physics dealing with the study of motion. No matter what your interest in science or engineering, mechanics will be important for you-motion is a fundamental idea in all of science. Mechanics can be divided into 2 areas-kinematics, dealing with describing motions, and dynamics, dealing with the causes of motion.
Dynamics (mechanics) Dynamics is the branch of applied mathematics (specifically classical mechanics) concerned with the study of forces and torques and their effect on motion, as opposed to kinematics, which studies the motion of objects without reference to its causes.
