Introduction to Shear Modulus Formula
Shear modulus tells how effectively a body will resist the forces applied to change its shape. When a shear force is applied on a body which results in its lateral deformation, the elastic coefficient is called the shear modulus of elasticity. It measures the rigidity of a body. Conceptually, it is the ratio of shear…

How to Calculate Work Done By Gravitational Force
In our day-to-day life, we see innumerable instances where gravity works with force. We know that in this universe there is a constant motion and force in the form of pushes and pulls. Among the many motions, there are four significant elementary forces, depending on which all sorts of phenomena are created. They are gravitational…

Concept of Heat of Fusion
The concept of heat of fusion can be understood as when the amount of energy required to melt a given quantity of a solid at its melting point temperature is measured by heat of fusion. In the other Words, when a certain mass of liquid transforms and solidifies, it also indicates the amount of energy…

Energy Density Formula
Energy density is denoted by the letter U. Magnetic and electric fields can also store energy. In the case of an electric field or capacitor, the energy density is given by UE = 1212εoE2 The energy density in the case of magnetic field or inductor is given by, UB = 12μ012�0 B2 Where UE =…

What is Energy Density?
Energy Density refers to the total amount of energy in a system per unit volume. (Even though generally energy per unit mass is also mentioned as energy density, the proper term for the same is specific energy. The term density usually measures the amount per unit spatial extension). Hence energy density is stored energy in…
