Random House Webster's College Dictionary
kin•e•mat•ics*ˌkɪn əˈmæt ɪks, ˌkaɪ nə-(n.)
the branch of mechanics that deals with pure motion, without reference to the masses or forces involved in it.
* (used with a sing. v.).
Origin of kinematics:
1830–40; < Gk kīnēmat-, s. of kinēma movement
the branch of mechanics concerned with motion without reference to force or mass
The branch of mechanics concerned with objects in motion, but not with the forces involved.
Origin: From κίνημα.
the science which treats of motions considered in themselves, or apart from their causes; the comparison and relation of motions
Kinematics is the branch of classical mechanics that describes the motion of points, bodies and systems of bodies without consideration of the causes of motion. The term is the English version of A.M. Ampère's cinématique, which he constructed from the Greek κίνημα, kinema, derived from κινεῖν, kinein. The study of kinematics is often referred to as the geometry of motion. To describe motion, kinematics studies the trajectories of points, lines and 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 to describe the motion of systems composed of joined parts such as an engine, a robotic arm or the skeleton of the human body. The study of kinematics can be abstracted into purely mathematical expressions. For instance, rotation can be represented by elements of the unit circle in the complex plane. Other planar algebras are used to represent the shear mapping of classical motion in absolute time and space and to represent the Lorentz transformations of relativistic space and time. By using time as a parameter in geometry, mathematicians have developed a science of kinematic geometry.
The Nuttall Encyclopedia
the science of pure motion under the categories of space and time, irrespective of consideration of the forces determining it and the mass of the body moved.
