What is Viscosity? Viscosity is defined as the quantity that represents a fluid’s resistance to flow. To put it in more simple terms, viscosity is the friction between the molecules of the fluid. We usually relate to the viscosity of a liquid by measuring the “thickness”. For example, we can state that honey is “thicker” (meaning…

The pressure is usually defined as the amount of force that is applied to a certain area. The pressure is a physical quantity and mostly expressed as formula p = F/A where F and A are force per area perpendicular to the surface. While we have already discussed everything about pressure in our earlier article,…

What is Lenz’s Law? Lenz’s law states that The induced electromotive force with different polarities induces a current whose magnetic field opposes the change in magnetic flux through the loop in order to ensure that original flux is maintained through the loop when current flows in it. Named after Emil Lenz, Lenz’s law depends on…

Faraday’s law of electromagnetic induction, also known as Faraday’s law, is the basic law of electromagnetism which helps us to predict how a magnetic field would interact with an electric circuit to produce an electromotive force (EMF). This phenomenon is known as electromagnetic induction. Michael Faraday proposed the laws of electromagnetic induction in the year…

In electromagnetism, Ampère’s circuital law relates the integrated magnetic field around a closed loop to the electric current passing through the loop. In this article, let us learn in detail about Ampere’s Law. What is Ampere’s Law? According to Ampere’s law, magnetic fields are related to the electric current produced in them. The law specifies…

We know light is the form of energy which can undergo various phenomenons like refraction, reflection, diffraction, and interference. In this session, let us know more about laws of reflection (first law of reflection and second law of reflection), types of reflection, examples, differences, and total internal reflection. What is Law of Reflection? Definition: The…

Kirchhoff’s circuit laws lie at the heart of circuit analysis. With the help of these laws and the equation for individual components (resistor, capacitor and inductor), we have the basic tool to start analyzing circuits. In this article, we will discuss Kirchhoff’s current and voltage law and how to employ them in circuit analysis. History…

Doppler effect or Doppler shift is a phenomenon that is observed whenever the source of waves is moving with respect to an observer. For example, an ambulance crossing you with its siren blaring is a common physical demonstration of the Doppler Effect. In this article, let us understand the intricacies of the Doppler effect in…

Archimedes principle deals with the forces applied to an object by fluids surrounding it. This applied force reduces the net weight of the object submerged in a fluid. In this article, let us familiarize ourselves with Archimedes principle. What is Archimedes Principle? Archimedes’ principle states that: “The upward buoyant force that is exerted on a…

While Newton’s laws of motion may seem obvious to us today, they were considered revolutionary centuries ago. The three laws of motion help us understand how objects behave when standing still, when moving and when forces act upon them. This article describes Sir Newton’s three laws and a summary of what they mean. Newton’s First…
