law in layman's terms

Introduction - For a layman the term 'work' implies any activity resulting in muscular or mental exertion. In physics, however, the term has a different meaning. It represents a physical quantity. When a force acts on an object, if the object moves in the direction of ..

Experimental study by Hooke revealed that elastic bodies regain their original configuration completely, only upto a limit. He termed this limit as the elastic limit. He found that within the elastic limit, the extension produced in the wire was directly proportional to the load app..

Amedeo Avogadro introduced the term "molecule" and distinguished it from 'atom'. According to Avogadro, particles in the gaseous state do not exist as atoms but as molecules. In 1811 he proposed his famous hypothesis, now known as 'Avogadro's Law'. As, it was found that even a f..

The incident ray, the refracted ray and the normal to the surface at the point of incidence all lie in one plane. For any two given pair of mediums, the ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant. The above law is called Snell's..

states that one quantum is absorbed by the molecule responsible for the primary photochemical process. After absorption, the excited molecule can then undergo various reactions. It can form a product, it can catalyze a chain reaction, or it can get de-excited. If on absorption of one photon, one ..

Ampere's law is a useful relation that is analogous to Gauss's law. Ampere's law is a relationship between the tangential component of magnetic field at points on a closed curve and the net current through the area bounded by the curve. Ampere's law is form..

Ohm's law is not a fundamental law of nature. There are a number of commonly used circuit elements which do not obey this law. They have one or more of the following properties: 1. V depends on I non-linearly. 2. The relationship between V and I depends on the sign of ..
