Rotational motion is more complicated than linear motion, and only the motion of rigid bodies will be considered here a rigid body is an object with a mass that holds a rigid shape, such as a phonograph turntable, in contrast to the sun, which is a ball of gas. Continuum mechanics deals with deformable bodies, as opposed to rigid bodies a rigid body is one where every atom is always in the same position with respect to every other atom in the body , even when outside forces are applied to the body a rigid body is a body that does not deform or vibrate. This course is an introduction to the study of bodies in motion as applied to engineering systems and structures we will study the dynamics of particle motion and bodies in rigid planar (2d) motion this will consist of both the kinematics and kinetics of motion kinematics deals with the.
