Dynamics is the branch of applied mathematics (specifically classical mechanics) related to the study of forces and pairs and their effect on motion, as opposed to kinematics, which studies the movement of objects without reference to their causes . Isaac Newton defined the fundamental physical laws governing the dynamics of physics, especially his second law of motion.
The study of dynamics is divided into two categories: linear and rotational. Linear dynamics belong to objects that move in a line and involve quantities such as force, mass / inertia, displacement (in units of distance), velocity (distance per unit time), acceleration (distance per unit of time squared) speed unit). Rotation dynamics refers to objects that rotate or move in a curved path and imply quantities such as torque, moment of inertia / rotational inertia, angular displacement (in radians or less frequently, degrees), angular velocity (radians per unit of time), angular acceleration (radians per unit of time squared) and angular momentum (moment of inertia multiplied by unit of angular velocity). Very often, objects exhibit linear and rotational motion.
For classical electromagnetism, it is Maxwell's equations that describe the dynamics. And the dynamics of classical systems involving both mechanics and electromagnetism are described by the combination of Newton's laws, Maxwell's equations, and Lorentz's force.
