ikkeelastiske

Ikkelastiske is a term used in physics and economics to describe a situation where a change in one variable has a proportionally smaller change in another variable. In economics, it specifically refers to situations where the quantity demanded or supplied of a good or service does not change significantly in response to a change in its price. This is often the case for goods that are necessities or have few close substitutes. For example, the demand for essential medicines is often considered ikkelastiske because people will continue to purchase them even if the price increases, as there are no readily available alternatives and they are vital for health. Conversely, if the price of a luxury item increases significantly, consumers may easily reduce their purchases or find alternatives, indicating a more elastiske demand.

In physics, the concept of ikkelastiske collisions refers to collisions between objects where kinetic energy is not conserved. While momentum is always conserved in a closed system, in an ikkelastiske collision, some of the initial kinetic energy is converted into other forms of energy, such as heat, sound, or deformation of the objects involved. A perfectly ikkelastiske collision is one where the colliding objects stick together after the collision, resulting in the maximum possible loss of kinetic energy. An example of an ikkelastiske collision is when a bullet embeds itself in a block of wood. The initial kinetic energy of the bullet is dissipated through friction and deformation as it comes to rest within the wood.
