What is Physics?

We can define Physics as the science that deals with matter, energy and their interactions. Physics functions in an exciting dimension. What we mean by this is that things keep changing in the world of physics with every new discovery. As the theories progress and new discoveries are made, not only the answer but the whole question changes. Due to this, many individuals try to define physics by what it was rather than what it is and will be.

Physics can be divided into various branches, and in modern days each branches has acquires a status of a full subject. The traditional branches or the main branches of classical physics are Mechanics, Optics, Thermodynamics, Electromagnetism, Acoustics. Some branches of physics are described below.

Why Is It Important To Study Physics?

Physics is one of the most important subjects in modern times. Everything we do in our day to day life is related to this subject. So why should we study physics? Some importance of studying the subject is given in the points below.

  • Without physics there would be no airplanes, cars, motorbikes, solar panels, computers, light bulbs, digital cameras, grocery laser scanners and much more.
  • Physics tries to define the universe in the simplest terms possible. That is done by specifying basic quantities and units, for instance – velocity, electric field and kinetic energy.
  • It also tries to find relations between fundamentally measurable quantities such as Newton’s laws of motion, special relativity and conservation of energy.

BYJU’S have introduced a new teaching method which includes video lessons with 3D animation and in-air projection technique which will ensure that learners can retain the concepts and ideas for a longer period of time. The teaching methods are designed in such a manner that kids fall in love with Physics.

Frequently Asked Questions on Physics

Why physics is important in our daily life?

Physics is important in our daily life because it explains the basic things that we do in life like what is the reason behind the twinkling of the stars, why we don’t fall while we are walking on the floor, why we tend to move forward when the bus stops suddenly, etc. Answers to all these questions and many others are obtained through Physics. Therefore, Physics is important in our daily life.

What are the five main branches of physics?

Following are the five main branches of Physics:

  1. Classical mechanics
  2. Quantum mechanics
  3. Electronics and electromagnetism
  4. Optics
  5. Relativity

How does physics relate to everyday life?

Following are the ways through which we can relate Physics to everyday life:

  1. Doppler effect is experienced when an ambulance passes by.
  2. Principles of optics are used in the cameras.
  3. The concept of magnetism and sound waves are involved in the working of earphones or headphones.

What is the main purpose of physics?

The main purpose of Physics is to explain how the entire universe works with the help laws, principles and theories.

What is physics and its importance?

Physics is defined as one of the branches of Science which explains the concepts that are related to matter and energy and their interactions. Following are the importance of Physics:

  1. It helps in understanding the fundamental laws of nature.
  2. It improves the quality of life by providing quantitative and analytical skills in the fields like engineering, medicine and science.
