ETYM French énergie, Late Lat. energia, from Greek energeia; en in + ergon work. Related to In, and Work.
Capacity for doing work. Potential energy (PE) is energy deriving from position; thus a stretched spring has elastic PE, and an object raised to a height above the Earth's surface, or the water in an elevated reservoir, has gravitational PE. A lump of coal and a tank of gasoline, together with the oxygen needed for their combustion, have chemical energy. Other sorts of energy include electrical and nuclear energy, and light and sound. Moving bodies possess kinetic energy (KE). Energy can be converted from one form to another, but the total quantity stays the same (in accordance with the conservation of energy principle). For example, as an apple falls, it loses gravitational PE but gains KE.
Although energy is never lost, after a number of conversions it tends to finish up as the kinetic energy of random motion of molecules (of the air, for example) at relatively low temperatures. This is “degraded” energy that is difficult to convert back to other forms.
So-called energy resources are stores of convertible energy. Nonrenewable resources include the fossil fuels (coal, oil, and gas) and nuclear-fission “fuels”— for example, uranium-235. Renewable resources, such as wind, tidal, and geothermal power, have so far been less exploited. Hydroelectric projects are well established, and wind turbines and tidal systems are being developed.
E=mc2 Einstein’s special theory of relativity 1905 correlates any gain, E, in energy with a gain, m, in mass, by the equation E = mc2, in which c is the speed of light. The conversion of mass into energy in accordance with this equation is the basis of nuclear power. The equation applies universally, not just to nuclear reactions, although it is only for these that the percentage change in mass is large enough to detect.

6. Enterprising or ambitious drive; SYN. push, get-up-and-go.
Any influence that tends to change the state of rest or the uniform motion in a straight line of a body. The action of an unbalanced or resultant force results in the acceleration of a body in the direction of action of the force, or it may, if the body is unable to move freely, result in its deformation (see Hooke's law). Force is a vector quantity, possessing both magnitude and direction; its si unit is the newton.
According to Newton’s second law of motion the magnitude of a resultant force is equal to the rate of change of momentum of the body on which it acts; the force F producing an acceleration a m s-2 on a body of mass m kilograms is therefore given by: F = ma See also Newton’s laws of motion.

ETYM Late Lat. intensitas: cf. French intensité. Related to Intense.
In physics, the power (or energy per second) per unit area carried by a form of radiation or wave motion. It is an indication of the concentration of energy present and, if measured at varying distances from the source, of the effect of distance on this. For example, the intensity of light is a measure of its brightness, and may be shown to diminish with distance from its source in accordance with the inverse square law (its intensity is inversely proportional to the square of the distance).

The ability to grow, reproduce, and respond to such stimuli as light, heat, and sound. It is thought that life on Earth began about 4 billion years ago. Over time, life has evolved from primitive single-celled organisms to complex multicellular ones. The earliest fossil evidence of life is threadlike chains of cells discovered in 1980 in deposits in nw Australia that have been dated as 3.5 billion years old.
Life originated in the primitive oceans. The original atmosphere, 4,000 million years ago, consisted of carbon dioxide, nitrogen, and water. It has been shown in the laboratory that more complex organic molecules, such as amino acids and nucleotides, can be produced from these ingredients by passing electric sparks through a mixture. It has been suggested that lightning was extremely common in the early atmosphere, and that this combination of conditions could have resulted in the oceans becoming rich in organic molecules, the so-called “primeval soup”. These molecules may then have organised into clusters capable of reproducing and of developing eventually into simple cells.
Once the atmosphere changed to its present composition, life could only be created by living organisms (a process called biogenesis).
It has also been suggested that life could have reached Earth from elsewhere in the universe in the form of complex organic molecules present in meteors or comets. This argument does not really offer an alternative explanation of the origins of life, however, as these primitive life forms must themselves have been created by a similar process.
Us weekly magazine of photo journalism, which recorded us and world events pictorially from 1936–72, 1978-. It was founded by Henry Luce, owner of Time Inc., who bought the title of an older magazine.
