•  Acceleration

  In physics, and more specifically kinematics, acceleration is the change in velocity over time. Because velocity is a vector, it can change in two ways: a change in magnitude and/or a change in direction. In one dimension, i.e. a line, acceleration is the rate at which something speeds up or slows down. However, as a vector quantity, acceleration is also the rate at which direction changes. Acceleration has the dimensions L T.

•  Invisible hand

  In economics, the invisible hand, also known as the invisible hand of the market, the term economists use to describe the self-regulating nature of the marketplace, is a metaphor first coined by the economist Adam Smith in The Theory of Moral Sentiments. For Smith, the invisible hand was created by the conjunction of the forces of self-interest, competition, and supply and demand, which he noted as being capable of allocating resources in society.
