1.2 Physics And Engineering

Physics generates fundamental knowledge that can be used by different 

branches of engineering.

Physics is an essential tool for the development and application of technology.

It helps understand the fundamental principles of the universe and apply them to create new and innovative technologies.

 Civil Engineering

It concerns designing and building skyscrapers , roads, bridges, dams, and railways using our physics knowledge of forces, fluid pressure, gravity.

Mechanical  Engineering

Mechanical engineering uses knowledge of physics to create mechanical systems like engines and vehicles.

Mechanical engineering use the physics concepts like mechanics, dynamics, thermodynamics, forces, stresses and aerodynamics to build:-

  • Aircraft

  • watercraft

  • engines

  • robotics

  • weapons

  • cars

  • Hydraulics and others.

Electrical engineering

Electrical engineering demands the understanding of some physics concepts like electromagnetism, mechanics, thermodynamics and others.

Electrical engineering involves designing electrical circuits including motors, electronic appliances, optical fiber networks, computers, and communication links. 

Chemical engineering

Chemical engineering involves the production of products through chemical processes. 


This includes designing equipment, systems, and processes for refining raw materials and for mixing, compounding, and processing chemicals.

Particularly, chemical engineering requires an understanding of the physical properties of molecules, the chemical bonds between atoms as well as the molecular dynamics which are dealt by molecular physics.

 Technology generating physics

Science and technology are two things that are completely interwoven. Science seeks to understand the natural world using technology.

Engineering uses scientific discoveries to design products and processes to solve 

the societal  problems. This Product And Processes Are What We Call Technology.

Technology Wouldn't exist without science and science wouldn't be as effective without technology.
