>>Elasticity may refer to: • Elasticity (physics), continuum mechanics of bodies that deform reversibly under stress Numerous uses are derived from this physical sense of the term, which is inherently mathematical, such as used in Engineering, Chemistry, Construction and variously in Economics.... Ex. Price elasticity of demand Main article: Price elasticity of demand Price elasticity of demand measures the percentage change in quantity demanded caused by a percent change in price. As such, it measures the extent of movement along the demand curve. This elasticity is almost always negative and is usually expressed in terms of absolute value (i.e. as positive numbers) since the negative can be assumed. In these terms, then, if the elasticity is greater than 1 demand is said to be elastic; between zero and one demand is inelastic and if it equals one, demand is unit-elastic. A perfectly elastic demand curve is horizontal (with an elasticity of infinity) whereas a perfectly inelastic demand curve is vertical (with an elasticity of 0). >>Sound is a mechanical wave that is an oscillation of pressure transmitted through some medium (like air or water), composed of frequencies within the range of hearing.[1] Ex. >>Acoustics >>MOTION In physics, motion is a change in position of an object with respect to time and its reference point. Motion is typically described in terms of displacement, direction, velocity, acceleration, and time.[1] Ex. Classical mechanics: Classical mechanics is used for describing the motion of macroscopic objects, from projectiles to parts of machinery, as well as astronomical objects, such as spacecraft, planets, stars, and galaxies. It produces very accurate results within these domains, and is one of the oldest and largest subjects in science, engineering, and technology. >>Modulus The mod operator takes two operands of integral type and calculates the modulus. The result of this operation is of integral type. The modulus operation is defined by Standard Pascal (ISO/IEC 7185) as follows: A term of the form i mod j shall be an error if j is zero or negative, otherwise, the value of i mod j shall be that value of (i-(k*j)) for integral k such that 0
