Physics is one of the most significant disciplines of natural science, which describe the nature and properties of matters. The term ‘physics’ is derived from the Ancient Greek word i.e. ‘phusikḗ’ meaning ‘knowledge of nature’. Definition Physics is the branch of natural science that studies the nature and properties of matter and energy. The significant subject matter of… Continue reading Introduction
Unit of Magnetic Field
When we talk about the magnetic field, different units are used to measure it. Basically, there are two systems of units based on the metric system used: the SI unit and CGS units. Thus, we will look at the unit of magnetic field below. SI Unit of Magnetic Field Generally, the magnetic field can be defined in… Continue reading Unit of Magnetic Field
Unit of Current
Introduction: We have heard a lot about electric currents in our classrooms as well as at home. While the topic is highly relatable, in more scientific terms an electric current is basically a flow of current or charge in electric circuits. Sometimes both ions and electrons carry the charge simultaneously. Electric current or charge is measured by an… Continue reading Unit of Current
Thermal Conductivity Unit
What Is Thermal Conductivity? Thermal conductivity is defined as the transportation of energy due to the random movement of molecules across the temperature gradient. In simple words, it is defined as the measure of a material’s ability to conduct heat. It is denoted by k. The inverse of thermal conductivity is thermal resistivity. It is… Continue reading Thermal Conductivity Unit
Unit of Heat
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… Continue reading Unit of Heat
Unit of Force
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,… Continue reading Unit of Force
Unit Of Energy
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… Continue reading Unit Of Energy
Unit of Density
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… Continue reading Unit of Density
Unit of Power
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… Continue reading Unit of Power
Unit of Viscosity
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… Continue reading Unit of Viscosity
