Physics is a study of energy, matter, and their interactions. It plays an important role in the future progress of the humankind. Physics interconnects with many interdisciplinary research fields like biophysics, quantum chemistry, etc. It is important to study physics at school for those who have the ambition to be at the front position of enhancing technologies and theories that explains our reality. It provides the students with problem solving, analytical, and quantitative abilities.

Importance of Physics in our daily life

All the activities in our daily life involve the application of physics. For example, ironing clothes, cooking, washing, answering a telephone call, listening to the radio, etc are some of the activities where we use the principles of physics.  Physics is involved in running automobiles and trains, moving objects, flying airplanes and kites, orbiting satellites, zooming jet planes, etc. Physics has applications in the construction of bridges, building, roads, houses, ships and boats. Knowledge of physics will help the common people to appreciate, comprehend and interact better with the environment. The laws of physics elucidate the principle behind the occurrence of thunder and lightening or a rainbow in the sky.

Many modern facilities like washing machines, refrigerator, and floor polishers make use of the principles of physics. Physics is also applied in the systems of communication, modern means of transportation, advancement in medicine, industry, and agriculture. So, it is a fact that all the amenities which make the life of common people more enjoyable and comfortable are based on solid principles of physics and its commercial applications.

Significance of Physics in the field of Engineering

Physics is the mother of all sciences. Mathematics and Chemistry are finally the derivates of Physics. Engineering is also a form of applied science with Physics as an important part. Initially, Engineering started with Mechanical and Civil engineering as the main branches. Both the streams are derivatives of Mechanics which in turn is a form of Physics. Hence, the two branches do not have any meaning without Physics. Civil engineering involves a major part of geology, which is also a derivative of Physics.

Another major part of engineering is Electrical engineering. This is a derivative of Electrical Physics. Since Electrical engineering leads to Electronics engineering and finally to Computer engineering and Information Technology, it can be concluded that the mother of all engineering branches is Physics. Recently, some other branches like Biomedical engineering and Bio-Technology have also been derived. These two streams are derivatives of Biology. Biology also has got thick links with principles Physics.  Both these branches are a blend of applied biology with principles of molecular physics. Thus, it is true that Physics has a significant role in Engineering.
