Dynamics is the branch of applied mathematics (specifically classical mechanics) that deals with the study of forces and pairs and their effect on movement unlike kinematics which studies the movement of objects without reference to their causes . Isaac Newton defined the fundamental physical laws that govern the dynamics in physics, especially his second law of motion.
In general terms researchers who participate in dynamics study how a physical system can develop or alter over time and study the causes of those changes. In addition Newton established the fundamental physical laws that govern the dynamics in physics. By studying your mechanics system you can understand the dynamics. In particular the dynamics is mainly related to Newton's second law of motion. However, the three laws of motion are taken into account because they are interrelated in any given observation or experiment.
The study of dynamics is divided into two categories: linear and rotational. Linear dynamics refers to objects that move along a line and involve quantities such as force, mass / inertia, displacement (in units of distance), speed (distance per unit of time), acceleration (distance per unit of time squared) ) and impulse (mass unit speed times). Rotational dynamics refers to objects that rotate or move in a curved path and involve such quantities as torque, moment of inertia / rotational inertia, angular displacement (in radians or less often degrees), angular velocity (radians per unit) of time), angular acceleration (radians per unit time squared) and angular momentum (moment of inertia per unit angular velocity). Very often the objects exhibit linear and rotational movement.
