Physics and other sciences
Physics has a strong relation with all other branches of science. The laws of Physics are generally used in all branches of science like Biology, Chemistry and Astronomy etc. etc.
Role of Physics in the development of technology and society
Like all other sciences, Physics has an important role in the development of technology. Physics has created a lot of knowledge and technology has successfully used that knowledge to invent machines. Machine makes human life comfortable. In this way Physics has a key role in the development and improving the quality of life.
