Kinematicsthe science of describing the motion of objects using words, diagrams, numbers, graphs, and equations. Kinematics is a branch of mechanics. The goal of any study of kinematics is to develop sophisticated mental models which serve to describe (and ultimately, explain) the motion of real-world objects.Scalarsquantities which are fully described by a magnitude (or numerical value) alone.Vectorsquantities which are fully described by both a magnitude and a direction.Upgrade to remove adsOnly \$1/monthDistancea scalar quantity which refers to "how much ground an object has covered" during its motion.Displacementa vector quantity which refers to "how far out of place an object is"; it is the object's overall change in position.Speeda scalar quantity which refers to "how fast an object is moving," can be thought of as therate at which an object covers distance.Velocitya vector quantity which refers to "the rate at which an object changes its position.
