ABSTRACT

Kinematics is the part of mechanics concerned with the description of movement. The term itself was coined in the mid-19th century by Ampère and stems from the Greek word , meaning to move.33 Kinematic quantities represent an exact geometrical description of spatial (3D) movement of the body; kinematics may therefore be called the geometry of movement. The kinematic description of movement encompasses positions, velocities, and accelerations of body segments and angles, angular velocities, and angular accelerations between segments. Accordingly, input data to the measurement system are some of the quantities mentioned, depending on the actual method.
