The gas constant is a physical constant denoted by R and is expressed in terms of units of energy per temperature increment per mole. It is also known as Ideal gas constant or molar gas constant or universal gas constant. The gas constant value is equivalent to Boltzmann constant but expressed as the pressure-volume product instead of… Continue reading Gas Constant

Stefan-Boltzmann Constant
In Physics, Stefan-Boltzmann Constant also known as Stefan’s constant is a physical constant. It is the constant of proportionality in Stefan-Boltzmann law of Blackbody radiation. Stefan Boltzmann Constant is denoted by Greek letter σ. This physical constant was formulated by Josef Stefan during 1879 and derived by Ludwig Boltzmann during 1884. Stefan Boltzmann Constant Value The… Continue reading Stefan-Boltzmann Constant
Neutron Mass
What are neutrons? It is a subatomic particle. Neutron is the composition of 1 up quark and 2 down quark and comes under the family of fermions. It is denoted by n or nº. The neutron mass is slightly higher than the proton mass. The charge of the neutron is null, which implies that neutron is… Continue reading Neutron Mass
Compton Wavelength
In physics, the Compton wavelength is the quantum mechanical property of a particle and is defined as the wavelength of the particle equal to the wavelength of the photon with same mass. It is well explained through the process called Compton scattering. The standard Compton wavelength is denoted by Greek letter λ (Lambda) measured using… Continue reading Compton Wavelength
Bohr Radius
In atomic, physics, Bohr Radius is a physical constant, expressing the most probable distance between the electron and the nucleus in a Hydrogen atom in the ground state. Denoted by ao or rBohr. Due to his prime role in building the Bohr model, This physical constant is named after him. Bohr Radius (ao or rBohr) The value… Continue reading Bohr Radius
Gravity Formula
We know gravity is the fundamental force and is the elemental concept of Physics. Gravity or gravitational force is the contribution of the great scientist Sir Isaac Newton. We know that dropping an apple from a tree was the reason for the inception of the Law of Universal Gravitation. In this session, let us learn… Continue reading Gravity Formula
Heat Loss Formula
Heat Loss Decrease of heat existing in space, resulting from heat transfer through roof, walls, windows and buildings surfaces or other factors is known as heat loss. Heat loss is determined by multiplying the values of the surface area, the difference in temperatures of indoors and outdoors and the value of heat loss of… Continue reading Heat Loss Formula
Friction Formula
Friction is the hindering force that comes into play when two items are interacting with each other. Friction formula is typically given as Ff = μFn The numeric’s are, the magnitude of friction is Ff , the coefficient of friction is μ and the magnitude of the normal force is Fn. The Normal force is equivalent to the weight… Continue reading Friction Formula
Resultant Force Formula
The resultant force is described as the total amount of force acting on the object or body along with the direction of the body. The resultant force is zero when the object is at rest or it is traveling with the same velocity as the object. The resultant force should be equal for all the… Continue reading Resultant Force Formula
Temperature Formula
Temperature is the degree or intensity of the heat present in a substance or a system, expressed based on the comparative scale and shown by a thermometer. In other words, Temperature is the measure of hotness or coldness of a body measured using Celsius, Kelvin, and Fahrenheit scales. The change in temperature is based on… Continue reading Temperature Formula
