Curie’s Law The Curie Law is defined as, in a paramagnetic material, the materials magnetization is directly proportional to an applied magnetic field, but the case is not the same when the material is heated. When it is heated, the relation is reversed. i.e. The magnetization becomes inversely proportional to the temperature. Where, M = Read more about Curie’s Law[…]
Relative Density Density is the ratio between the mass and the volume of a body. Relative density is the ratio between the density of an object and the density of some other reference object at some given temperature. . What is a Relative Density? Relative density also known as specific gravity, it is the ratio Read more about Relative density[…]
Thermal Conductivity Thermal Conductivity is the intrinsic property of a material which relates its ability to conduct heat. Heat transfer by conduction involves transfer of energy within a material without any motion of the material as a whole. Conduction takes place when a temperature gradient exists in a solid medium. Conductive heat flow occurs in Read more about Thermal Conductivity[…]
Electric Power Electric power is the rate at which work is done or energy is transformed in an electrical circuit. It is a measure of how much energy is used in a span on time. When a current “I” flows through a conductor for a time t, work done W is given by: W = Read more about Electric Power[…]
Avogadro Number Amadeo Avogadro first proposed that that volume of a gas at a given pressure and temperature is proportional to the number of atoms or molecules, regardless of the type of gas. Although he did not determine the exact proportion, he credited for the idea, that the number of entities in a substance is Read more about Avogadro Number[…]
De Broglie’s Equation In 1924 Louis de Broglie theorized that only light possesses both wave and particle properties, but rather particles with mass, such as electrons do as well. The wavelength of these material waves also known as the de Broglie wavelength. What is De Broglie’s Equation? The De Broglie equation is an equation used Read more about De Broglie’s Equation[…]
Unbalanced Forces Balanced forces do not cause a change in motion. When balanced forces act on an object at rest, the object will not move. If you push against a wall, the wall pushes back with an equal but opposite force. Neither you nor the wall will move. Forces that cause a change in the Read more about Unbalanced Forces[…]
Balanced Forces Force can be defined as that pull or push which produces or tends to produce, destroys or tends to destroy motion in a body, increases or decreases the speed of the body or changes its direction of motion. We apply force or force is applied to us in almost every aspect of our Read more about Balanced Forces[…]
Modulus of Rigidity The modulus of rigidity is also known as shear modulus. It is the material property with a value equal to the shear stress divided by the shear strain. It can be used to explain how a material resists transverse deformation but this is practical for small deformations only. What is Modulus of Read more about Modulus of Rigidity[…]
Rolling Friction Whenever the surface of an object slides over another, each object experiences a contact force. Which always opposes the relative motion between the surfaces, this contact force is called as frictional force. This force acts tangentially to the interface of two bodies. What is Rolling Friction? For a moving solid body, there are Read more about Rolling Friction[…]
