WebThe word ‘energy’ originates from the Greek energhéia, a concept Aristotle linked with the idea of hypothetical entities becoming real. It was applied by physicians until the 1600s to the notion of a supposed irritant substance conveyed by nerves that stimulated action. Aspects of the concept of work done appear as early as 60AD in the ... Web1 N m is 1 Joule (J) the preferred unit for work and energy (more on this later): Work = 564 J (Without cos θ, the wrong value would be 600 J) Here are some other angles: cos(0°)=1 : cos(60°)=0.5 : cos(90°)=0 : ... when falling down it has kinetic energy (the energy of motion) Energy goes from one storage to another, or goes to heat:
