Kinematics is a branch of classical mechanics that describes the motion of points, bodies (objects), and systems of bodies (groups of objects) without considering the mass of each of the forces that caused the motion. It sounds confusing, right? Well, relax and take the quiz to test your knowledge of kinematics.
