origin of law

Hooke's law - 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 proportion..

Robert Boyle proposed this law in the year 1662, giving the relationship between pressure and volume of given mass of a gas at constant temperature. This law states that volume (V) of a given mass of gas is inversely proportional to the pressure (P) at constant temperature. Math..

Consider a particle A having linear momentum and radius vector with respect to the origin as given in the figure. After a time D t, the particle is at B and the radius vector becomes + D . The velocity of the particle has a radial component v r and an angular component v f ..

Ultrasonic waves are transmitted through the ocean and if on its path any submerged objects are encountered, then as per law, the waves are reflected back to the origin. The time of sending the wave and the time of receiving the reflected wave are worked out and the distance of ..

>In the early seventeenth century the German astronomer, Johann Kepler, had shown that the planets move in elliptical paths or orbits round the sun, but he was unable to explain why. It was left to Sir Isaac Newton to offer a satisfactory explanation based on the first law of motion and t..

Force Due to a Coiled Spring - Springs are simple devices that are commonly used. It is used in shock absorbers in automobiles, in push-back ballpoint pens, in electrical measuring instruments, etc. The spring possesses a simple property by the virtue of which, when compressed or elongated, it trie..

Now that we understand the importance of friction, let us understand its origin. Take two pieces of sandpaper facing each other. Now bring them in contact with each other and try to rub them against each other. You will find it difficult to move. Why do you think so? The answer is that ..

The law of conservation of energy states that whenever one form of energy is lost, an equivalent amount of energy in another form appears, i.e. the energy is always conserved. If it were so, then there should have been no energy crisis? As our experience is altogether different, the expl..

Consider a reversible reaction expressed by the following general equation: where A and B are two substances which react to form new substances C and D and C and D react under the same conditions forming the original substances A and B. Let us assume that the concentrations of these four ..
