Dynamics comprises kinetics and kinematics. In practice, the difference between kinematics and kinetics is the way of looking at the same machine or component. Kinematic questions only consider the geometry of the motion. Kinetics also takes into account the cause of the motion.
The aim of dynamics is to calculate the stress and strain on components or systems in order to be able to design them.



Various movements are displayed graphically and studied using kinematic models.

Vibration is the process occurring when a physical quantity periodically changes depending on time. This is associated with a conversion of energy from one form to another. In the case of mechanical vibrations, periodic potential energy is converted into kinetic energy and the reverse.
