Motion (physics) - Kinematics

Kinematics

Kinematics applies geometry to the analysis of movement, or motion, of a mechanical system. Rest and motion is a very relative term as far as the frames of reference is concerned.So, while proceeding with any of the problems in kinematics one should be very careful about the frame of reference. The rotation and sliding movement central a mechanical system is modeled mathematically as Euclidean, or rigid, transformations. The set of rigid transformations in three dimensional space forms a Lie group, denoted as SE(3).
