Basics of Physics

By Knowledge Flow

The Basics of Physics book covers everything from light and sound to nuclear science and geology. Physics have several branches including optical science, quantum mechanics, thermodynamics, electromagnetism and a unique field fluid mechanics. These branches of physics are broad and complex, studied by various different types of scientists and engineers.
These fields help to describe how object and energy move around the world through our most important senses. This Basics of Physics book describing the scientific study of matter and energy and covers various key concepts of science and engineering.

Fundamental Concepts

Introduction

P

hysics is a branch of science but science works on the scientific method. Physics is the study of matter, energy, force, logic, reason and the interaction between them and is asking fundamental queries and trying to understand to find its answer by observing and experimenting. The scientific principles accept only reason, logic, and experimental proof to tell between what is scientifically done and what is not.

The word "Physics comes from the Greek word knowledge of nature" and the field achieves to understand and analyze the natural phenomena of the universe. Physics is based on many scientific laws and these laws like gravity and Newton's laws of motion are scientifically proved that they are trusted as truths and they can be used to help us to imagine how the things will behave. Without physics we could not study on biology, chemistry or anything.

History

In the Ancient Greeks the early physics to be the found and they were better analyzed and understand the natural world around them. They were established the first quantitative physics laws known as Archimedes principle levers and the bounce of bodies in water. But they did not actually conduct experiments, and physics as science stagnated for many centuries

Modern physics have started around the 20th century with famous legend such as Galileo, Copernicus, Newton, Faraday and Maxwell. They were discovered more and more about our universe.

By the 16th century Copernicus was first discovered that the earth revolves around the sun, not the other way around.

By the 17th century Galileo was discovered many fundamental of physical and also described many astronomical concepts such as planetary satellites and sunspots using telescope.

During 17th century Isaac Newton was described three famous laws of motion and the law of gravitation. Newton is also founder of calculus.

Faraday and Maxwell were demonstrated laws of magnetism, electricity and electromechanical waves in the 1800s.

Branches of Physics

The fundamental physics divided into some categories:

Classical Mechanics — this branch deals with the motion of bodies under the action of forces and this branch is also known as Newtonian mechanics.

Electromagnetism — objective of this branch is to study how charges works under the effect of electric and magnetic fields and analyze how charges can build these fields.

Thermal Physics — objective of this branch is to study the behavior of heat.

Quantum Mechanics — in which primarily study of small objects such as
