Q.1 How does physics play an important role in our life?

Ans: Physics in Science:
Physics is the most fundamental of all the sciences. To study biology, chemistry, or any other natural science, one should have a firm understanding of physics principles.
Example:
For example, biology uses the physics principles of fluid movement to understand how the blood flows through the heart, arteries, and veins. Chemistry relies on the physics of subatomic particles to understand why chemical reactions occur.

Physics and Technology:
Rockets and space shuttles, Magnetically levitating trains, and microscopic robots that fight cancer cells in our bodies. All of these technologies, whether commonplace or exciting, are based on the principles of physics.
Physics is behind every technology and plays a key role in the further development of these technologies, such as airplanes, computers, PET scans, and nuclear weapons.

Physics and Society:
Apart from playing a significant role in technology, professionals such as engineers, pilots, physicians, electricians, and computer programmers apply physics concepts in their daily work.
Example:

For example, a pilot must understand how wind forces affect a flight path. Thus advancements in physics change the role of trained professionals and create new job markets. Research in physics helps to develop the consumer goods that we use at home, thereby improving our standard of living.
