Kinematics (from Greek κινεῖν, kinein, to move)'s the branch of classical mechanics that describes the motion of objects without consideration of the causes leading to the motion. Linear or translational kinematics's the description of the motion in space of a point along a line, also known as trajectory or path. This path can be either straight (rectilinear) or curved (curvilinear). There're three basic concepts that're required for understanding linear motion: Di… (More on Kinematics)
