What is Current Electricity? Current electricity is defined as the flow of electrons from one section of the circuit to another. Electromotive Force (EMF) and Voltage: When two bodies at different potentials are linked with a wire, free electrons stream from Point 1 to Point 2, until both the objects reach the same potential, after… Continue reading Current Electricity

Work, Energy and Power are fundamental concepts of Physics. Work is the displacement of an object when a force (push or pull) is applied to it. We define the capacity to do the work as energy. Power is the work done per unit of time. This article discusses work, energy and power in detail. What… Continue reading Work, Energy and Power

Aristotle famously represented a force as anything that causes an object to undergo “unnatural motion”. Sir Isaac Newton was one of the first scientists to study gravity and force. Any kind of force is just a push or a pull. It can be described as a push or pull on an object. What is Force? Push or… Continue reading Force

The concept of motion in physics is one of the important topics under Classical Mechanics. Did you know that everything in the universe is always moving? Even if you are completely still, you still belong to the earth which is continuously moving about its axis and around the sun. Motion means a change in the… Continue reading Motion In Physics

Thermodynamics deals with the concepts of heat and temperature and the inter-conversion of heat and other forms of energy. The four laws of thermodynamics govern the behaviour of these quantities and provide a quantitative description. William Thomson, in 1749, coined the term thermodynamics. What is Thermodynamics? Thermodynamics in physics is a branch that deals with… Continue reading Thermodynamics

Sound is the form of energy which can be transmitted from place to another. Sound is a form of pressure wave created by a vibration of an object. Sound carries energy and has wide application in our daily life. The science of sound is known as acoustics. In this article, let us study in detail… Continue reading Acoustic

Introduction to Relativity Relativity is a theorem, formulated by Albert Einstein, which states that space and time are relative and all the motion must be relative to a frame of reference. It is a notion that states, laws of physics are the same everywhere. This theory is simple but hard to understand. It states: There… Continue reading Relativity

Electromagnetism is a branch of Physics, that deals with the electromagnetic force that occurs between electrically charged particles. The electromagnetic force is one of the four fundamental forces and exhibits electromagnetic fields such as magnetic fields, electric fields, and light. It is the basic reason electrons are bound to the nucleus and are responsible for the… Continue reading Electromagnetism

Introduction Like all the different types of light, the spectrum of visible light is absorbed and emitted in the form of tiny packets of energy called photons. These photons have both the properties of a wave as well as a particle. Hence this type of property is called wave-particle duality and the study of light in the area of… Continue reading Optics

Mechanics is the branch of Physics dealing with the study of motion when subjected to forces or displacements, and the subsequent effects of the bodies on their environment. There are two sub disciplines Classical Fields and Quantum Fields Classical mechanics Classical mechanics deals with the question of how an object moves when it is subjected to various forces,… Continue reading Mechanics
