Introduction
Physics is a branch of Science, where occurrence of anything (Physical, Mechanical, Chemical) is governed by principles, deduced either experimentally or theoretically. Physics is the study of the reason or cause of any changes. Its study includes vast variations ranging from small atomic structure to ever expanding universe. Each and every creature has experienced the effects of any laws explained in Physics in their life, so it's become very important to study and understand life governing “Fundamentals of Physics”. In this introductory chapter we will study Principles of Physics, observe some basic law of physics and its resemblance in our daily lives. We will study basic Physics and the nature of Physical laws.

What are Laws?

It is basically a conclusion drawn from the past references of scientific experiments and observation. These laws are being continuously checked or they are being under evaluation for proper validation. Broadly speaking study of Physics has been classified as:

  • Classical Physics
  • Atomic Physics

Principles of Physics

Any laws that we study in Physics are governed by its principles. According to Physics the physical laws of matter, energy and the fundamental forces of nature govern the interactions between different entities.

Important Laws of Physics

Here, we will see some basic physics laws for which they exist in our surroundings.

  • Newton’s laws of motion
  • Conservation of energy
  • Laws of Friction
  • Archimedes Principles
  • Faraday’s laws
  • Laws of Thermodynamics

Apart from above mentioned Laws, there are numerous laws left behind.

NCERT Physics Notes :

How Laws are formulated?

For any assumptions to be formulated as Laws it should follows:

  • Must exist in confined (given) Space and Time.
  • Conservative in the state of quantity.
  • True, and must hold verification under specified condition
  • Must be derived in simplest form.

Nature of Physical laws

As we have studied before, laws are encapsulated from the conclusion drawn from the past references and their universal acceptance.
