At the dawn as a social science, economics was defined and discussed at length as the study of production, distribution, and consumption of wealth by Jean-Baptiste Say in his Treatise on Political Economy or, The Production, Distribution, and Consumption of Wealth (1803).
Kinetic energy. In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes.
the energy possessed by a body or object due to movement. Can be translational or rotational (or both). translational kinetic energy the energy possessed by an object due to its movement along a straight or a curved line. May be calculated as Â½ mv2 where m is the mass of the object and v is linear velocity. rotational kinetic energy the mechanical energy possessed by an object due to its rotation about an axis.
