# What is Physics – A Short Introduction

by
The origin of the word physics came from Greek language physics, which means nature! In the ancient definition of physics, physics is an important branch of science in which nature and its philosophies are studied! But in the modern definition of physics, the study of the substances and energy and the relationship between them is called physics!
 
# What is Physics - A Short Introduction
 
The definition of physics comes from two words – 
  • Matter
  • Energy

Meaning of physics

What is the substance?

 
The substance is called the object in which weighing and covering the area, it is called a substance. This means that there are substances from earth to dusty soil. Anything that is not weighted can not be called substance! The substance can neither be made nor can it be useless in some way, it can be changed from just one stage to another!
 
What is energy?
Energy is called the ability to work, without any energy, no work is possible! Energy can not be made nor can it be useless, it can be converted from one form to another!

Relationship between matter and energy

Newton and Einstein are considered to be the father of physics, both of these are considered as parents! We will try to tell you this! The power of force and displacement is called work or energy! If force is applied in any object and its displacement, it is said that due to the energy it has accelerated, this knowledge has been explained by Newton in its motion law! E in Equal to Mc Square, Einstein has clearly told how the substance changes in energy! The concept of the father of both physics clearly shows that there is a connection between matter and energy! In today’s physics we read, we have to study matter and energy!

 
Mechanical, sound, heat, electricity and light energy, etc. are produced from the substance! From energy origin to philosophy of use, the study is done in physics! Physics Today classical physics and modern physics is divided into!

Classical physics

Principles of electromagnetism of Newtonian mechanics, thermodynamics, and Maxwell are all examples of classical physics. In the classical physics of body and forces, especially Newton shows the laws of motion and mechanics based on them.

Modern physics

Albert Einstein, a father of modern physics, was a 20th-century scientist who came with some important ideas in modern physics such as the theory of relativity and the famous equation E = MC2. “Modern” physics means physics based on the first two major successes of the twentieth century: relativity and quantum mechanics.
