INTRODUCTION
Kinematics is the branch of mechanics which studies the motion of objects without considering the forces that cause the motion. Vector quantities such as displacement, velocity, and acceleration are involved. The study of the motion of objects under the action of forces is called dynamics. The study of the motion of objects, and the related concepts of force and energy, form the field called mechanics. Mechanics is customarily divided into two parts i.e. kinematics and dynamics. • Kinematics : the description of how objects move. Kinematics in one dimension : describing an object that moves along a
