Physics is the fundamental science that explores the structure of matter and the interactions between its basic constituents across the observable universe.
It delves into both macroscopic and submicroscopic realms, aiming to understand the behavior of objects under various forces and the origins of fundamental force fields such as gravity, electromagnetism, and nuclear forces. At its core, physics seeks to formulate comprehensive principles that unify disparate phenomena.
The subject of physics encompasses numerous branches, each focusing on specific aspects of nature. These branches have evolved to encompass a vast array of phenomena, providing insights into the workings of the physical world.
Among the traditional branches are classical physics, which includes mechanics, optics, acoustics, and electromagnetism.
Each branch of physics contributes to our understanding of the universe, addressing questions ranging from the origins of the cosmos to the behavior of subatomic particles.
Through continuous exploration and experimentation, physicists strive to open the mysteries of nature and uncover the underlying principles governing the physical world.
Newton’s Laws of Motion are the concepts of Sir Isaac Newton formulated in the 17th century. It consists of three basic laws which describe different forces that act on a body. Thus, the body either in rest or motion reacts … Read more
What is a Hysteresis Curve? The word ‘hysteresis’ simply means lagging. In electromagnetism, it is a very useful analysis which suggests the lag of magnetic flux density (B), when magnetic field strength (H) is applied. It is observed that the … Read more
What is the Biot-Savart Law? The Biot-Savart Law is a principle in electromagnetism that deals with the quantitative and qualitative nature of magnetic fields produced by a steady electric current. Hence it provides an empirical relationship between the electric current … Read more
Introduction to Faraday’s Laws of Electromagnetic Induction Faraday’s law of electromagnetic induction or simply known as Faraday law, is an explanation of the direction of electric and magnetic fields. It describes the behavior of the magnetic field when it interacts … Read more
What are Gravitational Waves? Gravitational waves come from the general theory of relativity. They propagate the solution of Einstein’s field equations that describe gravity. Einstein predicted this wave 100 years ago, and it was first discovered on September 14, 2015. … Read more
What is a Transistor? A transistor is a three-terminal semiconductor device used to amplify or switch electrical signals and power. It is one of the most essential tools in electronics. The power provided to one terminal is regulated by the … Read more
A Superconductor is a superior conductor whose resistance attains a zero resistance after reaching a specific temperature and hence provide nearly a 100% of efficiency in transmission of electricity. This amazing property of a conducting substance allows current to flow … Read more
The laws of conservation of energy are basically the principles, governing all the energies existing in the universe. The statement of the law is given for a closed system as ‘energy can neither be created nor destroyed-it transforms from one … Read more
An electric charge is stored in an electric field by a simple electric device called a capacitor. A dielectric material separates the two conductive plates that jointly make a capacitor. An electric potential difference arises from the plates becoming oppositely … Read more
