We are all familiar with the term heat, and we experience the effect of heat almost every day in our lives. As we are so familiar with the topic if we look at the science behind it, heat is the form of energy that changes the temperature in any substance. Heat involves the transfer of…

We all know who Isaac Newton is and it was his research that led to the establishment of the popular formula F = ma representing acceleration and mass of an object when force is applied. While students can check the article on force in detail, here we will learn about the unit of force. Well,…

Energy, in simple terms, can be defined as the capacity for doing work. It can occur in kinetic, potential, electrical, chemical, nuclear, thermal, and other forms. It is classified as renewable energy and non-renewable energy. Further, in this article, we shall discuss the various units of energy. What is the SI Unit of Energy? Following is the…

What is Density? The density of material shows the denseness of that material in a specific given area. A material’s density is defined as its mass per unit volume. Density is essentially a measurement of how tightly matter is packed together. It is a unique physical property for a particular object. The principle of density…

Power, in general, is defined as the rate at which energy is transferred or converted or the rate of doing work. Thus, power can be calculated using the formula P = W / t. On the other hand, power is a scalar quantity and is basically the amount of energy consumed per unit time which…

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…
