introduction with laws

Introduction - Newton's Law of Motion - Whenever we push or pull an object, we do so by means of a force. Force is an interaction between two bodies which causes acceleration, or simply, motion. The relationship between force, acceleration and motion was studied by Sir Isaac New..

Introduction - The word force in common usage refers to a push or pull. The word Mass is also just as familiar as the word force. A super tanker is one that contains an enormous amount of mass. In comparison a coin does not contain much mass. During the seventeenth century Newton develope..

Introduction - The branch of chemistry, which deals with energy changes during various physical processes and chemical reactions, is called chemical energetics. All chemical reactions are normally accompanied by energy changes. These energy changes take place because energy is needed to b..

In the year 1801, Robert Boyle and Charles had deduced the gas laws and proved them. They had confirmed that equal volumes of all the gases behave similarly, under similar conditions of temperature and pressure and the volumes of reacting gases and their gaseous products are in ratio of s..

The goal of physics is to provide an understanding of nature. The science of physics was developed to explain our physical environment. Great Physicists like Galileo, Newton, and Einstein etc. framed laws to explain the various phenomena in nature. These laws have been verified ..

We have already studied the 'Periodic Classification of Elements' in standard ninth. We know that the periodic table is the arrangement of Elements into periods and groups on the basis of their electronic configuration. The Modern Periodic Table follows the 'Modern Periodic Law' i.e., "Th..

The phenomenon of electrolysis is an important chemical effect of electric current. In a metallic conductor, the electric current is due to the drifting of free electrons, there is no chemical or physical change, only the generation of heat. However, in ionic solutions (electrolytes), the electric ..

If m is a positive integer, a x a x a . m times is written as a m . a is called the base and m is the power. We read it as "a raised to the power m". The power is also called "the index" or "the exponent". When the power or index is a fraction say then and it is a surd of order n. In this chapter w..

The evidence of the electrical nature of matter preceeded the first theories about the structure of matter. In 1832, Michael Faraday discovered electrolysis. He gave the first important clue relating electricity to matter and about the electric nature of atoms. Faraday enunciated two laws..
