What is physics? |
Physics is the study of the structure of the natural world. It seeks to explain natural phenomena in terms of a comprehensive theoretical structure in mathematical form. Physics depends on accurate instrumentation, precise measurements, and the expression of results in mathematical terms. It describes and explains the motion of objects that are subject to forces. Physics forms the basis of chemistry, biology, geology, and astronomy. Although these sciences involve the study of systems much more complex than those that physicists study, the fundamental aspects are all based on physics.
Physics is also applied to engineering and technology. Therefore a knowledge of physics is vital in todayâ€™s technical world. For these reasons physics is often called the fundamental science.
