Document Summary
Scientists are people trained in science and who practice the knowledge of science. We require people in industries to work as engineers, technicians, researchers, in hospitals as doctors, nurses and technologis ts. Science gives us powerful ideas, instruments and methods which affect us in our daily lives. Physics is a greek word meaning nature hence it deals with natural phenomena. Physics is therefore a science whose objective is the study of components of matter and their mutual interactions. Physics is also defined as the study of matter and its relation to energy. A physicist is able to explain bulk properties of matter as well as other phenomena observed. It contains a significant portion of charged particles ions and/or electrons. Since physics enables us to understand basic components of matter and their mutual interactions it forms the base of natural science. Biology and chemistry borrow from physics in explaining processes occurrin g in living things and organisms.
