Dynamics Kinematics Description of geometric and time-dependent aspects of motion without dealing with forces causing the motion Translation (or linear) motion Angular General: Translation (or linear) motion + Angular Study of the relation among position, velocity and acceleration The relation: form of differential and integral equations Kinetics Kinematics + force and moment that cause the motion Use Newton’s 2 nd law of motion Study of the relation among position, velocity and acceleration and force that cause the motion The relation: more different forms Translation (or linear) motion Angular General: Translation (or linear) motion + Angular

Dynamics Translation (or linear) motion All parts of a body move at the same distance for a given time and in the same direction Example: elevator Linear motion does not imply movement along a straight line: for a given time interval it can move in one direction, and then move to a different direction in another time interval. Example moving a body in different street and avenue
Dynamics Angular motion A body moves in a circular path such that all parts of the body move through the same angle as the same time The motion occurs about a central line, known as axis of rotation The axis is perpendicular to the plane of the motion
