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 straight line path, which is one dimensional motion . & Kinematics in two dimensions : the description of the motion of objects that move in paths in two (or three) dimensions . • Dynamics : deals with force and why objects move as they do. In this part we will solve the following questions : & What makes an object at rest begin to move ?...
