Kinematics refers to the study of motion in a system of bodies, which does not directly take into account the potential fields or forces influencing the motion. It uses numbers, words, equations, diagrams, and graphs to explain the motion of objects. Kinematic motion can be influenced by three different types of forces, which include gravity, contact force, and fluid pressure. In astrophysics, kinematics is used to explain the motion of celestial bodies and groups of such bodies. Kinematics of machines is the study of the relative motion of machine parts. It entails the investigation of displacement, acceleration, position, and velocity of machine parts. The information on these aspects of machines is useful for designing the mechanism of machine. This book covers in detail some existent theories and innovative concepts revolving around the kinematics of machinery. It aims to shed light on some of the unexplored aspects of this area of study and the recent researches in it. The book will provide comprehensive knowledge to the readers.
