Kinematics is the branch of classical mechanics which describes the motion of points, bodies (objects), and systems of bodies (groups of objects) without consideration of the causes of motion. [ 1] [ 2] [ 3] Kinematics as a field of study is often referred to as the "geometry of motion". [ 4] [ 5] [ 6] For further details, see Analytical dynamics . To describe motion, kinematics studies the trajectories of points, lines, other geometric objects, and their differential properties such as velocity and acceleration. Kinematics is used in astrophysics to describe the motion of celestial bodies and systems, and in mechanical engineering , robotics , and biomechanics [ 7] to describe the motion of systems composed of joined parts (multi-link systems) such as an engine , a robotic arm or the skeleton of the human body. The study of kinematics can be abstracted into pure...
