the name itself suggest that dynamics means motion or flow the variables which are responsible for motion includes like temperature ,pressure ,viscosity ,flowrate etc., these variables are at any time with in our control that means to bring the system to stable positions can be achieved by monitoring the parameters which effects the system that in term causes the system to move away from the set point condition there plays a vital role of process dynamics control.
In the field of chemistry and engineering, the time between 1750 and 1900 was an exciting one. Those years saw the invention of the battery, miner's lamp, many interchangeable parts, and the electric light.
Micromotion Study Micromotion study, which was originated by Frank B. Gilbreth, is one of the most exacting forms of work analysis available for job improvement. It is an analysis technique making use of motion pictures (or videotape) taken at a constant and known speed. The film becomes a permanent record of both the method being used and the time consumed in doing the work. Although micromotion study formerly made use of motion pictures, very few companies today are using them. As indicated earlier, videotape equipment has been developed so extensively that it has virtually supplanted the use of the motion picture camera. Further it is so cheap and easy to use that it makes the older approach archaic. Micromotion study provides a valuable technique for making minute analyses of those operations that are short in cycle, contain rapid movements, and involve high production over a long period of time. Thus it is very useful in analyzing operations such as the sewing of garments, assembly of small parts and similar activities.
Technology has taken human from land to sky. Today almost in every field we can see its impact. It is not different with agriculture. New technological machines can do the same work in an hour which will be difficult for man farmers to do in almost a day. Earlier sickle was used for harvesting but now we have developed harvesters. It certainly helps our production to increase many folds in a small period of time.
normal time is calculated by... average cycle time x (% rating factor/100)

Disadvantages of time and motion studies include outdated methods of thinking and the belief that there should be a separation between thinking and working. Attempts to discredit these studies point to these critiques.
Time and motion studies address the issues of industrial production and efficiency, since they attempt to measure time on task, product quality, and worker safety
Motion is related to a change in position of an object with respect to time. Motion is typically described in terms of velocity
Micromotion is a type of periodic motion that occurs for short periods of time. When used in studies, it involves using some kind of timing gadgets or motion-videos to analyze certain happening, usually related to work.

The scientific beginning of psychology is often traced back to Wilhelm Wundt who established the first psychology laboratory in Leipzig, Germany in 1879. Wundt is considered the father of experimental psychology, as he emphasized the importance of using scientific methods to study mental processes.
