Kinematics
Kinematics is a section of mechanics in which the motion of material bodies in a space is studied from a geometric point of view, that is, not taking into account the forces that determine this movement. For the first time this concept was introduced by Andre-Marie Ampere. Kinematics is also called the section of hydromechanics, the dynamics of liquids, in which the motion of a fluid is studied without taking into account the forces that determine this movement. Kinematics examines the mechanical motion of the bodies, without considering the reasons that caused it. The description of the mechanical motion in kinematics is based on the clarification of the nature of the changes with the time coordinates, displacements, velocities. In order to describe the movement of the body, it is necessary to establish the law of time-varying coordinates or body velocities relative to other bodies.
