However, the woman using the pulley has generated more power. Energy Give an example of something we think of as work in everyday circumstances that is not work in the scientific sense. 59. Is energy transferred or changed in form in your example? The measurement of work and energy with the same unit reinforces the idea that work and energy are related and can be converted into one another. 68. See the discussion of useful work in Work, Energy, and Power in Humans. The avalanche releases a great amount of energy. Since work is a scalar quantity, therefore, power is also a scalar quantity.SI unit of power is the watt (W).
