Physics is the study of matter and its motion through space and time, energy and force. Physics is considered a fundamental science because its laws and theories play an important role in other sciences.
Classical Physics include the study of such areas as acoustics, optics, mechanics, and thermodynamics. These are areas that can be observed with minimal technology. Modern Physics expands the study into areas not observable without the use of highly specialized technology and includes areas such as atomic and nuclear physics, cryogenics, solid-and particle physics.
Physicists explore the connection between the most fundamental aspects of the natural world and the universe and develop explanations for these phenomena. Because of this, Physics is an integral part in the development of new technology and the basis of engineering.
