##### What is Physics?

The work ‘Physics’ has originated from Greek work fusis, meaning nature. So, in physics we deal with nature and natural phenomena. We understand nature only through the study matter, energy and their interactions.

###### Branches of Physics

Mechanics and properties of matter, Heat and thermodynamics, Sound or acoustics, Electricity and magnetism, Modern physics, Biophysics, Astrophysics, Geophysics, Nuclear physics, etc.

Theories of Physics

*Classical Mechanics*: It explains the motion of particles which travel with velocities much less than that of light.- Theory of Relativity: It explains the in-variance in nature and also the motion of particles which travel with velocities close to that of light.
*Thermodynamics*: It is the theory of heat, temperature and conversion of heat into work and vice-versa. It also explains the behaviours of systems containing very large number of particles.*Electromagnetism*: It is theory of electricity, magnetism and the electromagnetic radiation including optics.*Quantum Mechanics*: It explains the behaviours of atomic and subatomic systems of particles.

According to Albert Einstein, Science is not just a collection of laws, a catalogue of unrelated facts. It is a creation of human mind with its freely invented ideas and concepts. About modern physics, he said, the reality created by modern physics is indeed, far removed from the reality of the early days.

###### Simplicity of Physics – Physics is a basic Science. Why?

The animate and ananimate – all objects are made up of matter and energy. Therefore, any type of study of an object is basically the study of some manifestation of matter and energy. The matter and energy is the subject of study of physics, hence the laws of physics are at work at the root of the all sciences. Therefore, it need not be surprising if some direct modification of the laws of physics appear to be underlying the human behaviour also. Due to these reasons physics has intimate relationship with all the sciences and hence it is called a fundamental science.
