# Physics Definition, What Is Physics

### What is Physics?

It is simply the study of the world around us. For example: when a ball is thrown up in the air comes back to the ground the study of motion of this ball is physics, the study of elasticity of spring is physics, the study of twinkling of stars is physics. The word physics itself is of Greek origin, and it means nature. Among the Sciences, it is considered to be the oldest. This is because, according to current records, the beginning is marked with people observing the moon and therefore delving into astronomy. Of course at this point of time everything was just theories and assumptions till the Scientific Revolution began. We can say that it is simply the study of matter and energy around us, and how they interact and influence each other.

### Physics through the words of popular physicists:

There are many big names, Galileo Galilei, Isaac Newton, Albert Einstein, Richard Feynman and so many others when it comes to the world of science. Of course many people do not limit themselves to just one of the sciences because they are all interconnected. These scientist have contributed much to the world of science leading to many discoveries and their advancements through decades.

This is a quote by the famed quantum physicist, Richard Feynman

“Science is a way to teach how something gets to be known, what is not known, to what extent things are known (for nothing is known absolutely), how to handle doubt and uncertainty, what the rules of evidence are, how to think about things so that judgments can be made, how to distinguish truth from fraud, and from show.”

### Branches of Physics:

● Classical Mechanics
