Kinematics

Kinematics is the description of motion. The motion of a point particle is fully described using three terms - displacement, velocity, and acceleration. For real objects (which are not mathematical points), translational kinematics describes the motion of an object's center of mass through space, while angular kinematics describes how an object rotates about its center of mass. In this section, we focus only on translational kinematics.

Displacement, velocity, and acceleration are defined as follows.
