A watt-second (symbol W s or W⋅s) is a derived unit of energy equivalent to the joule. [34] The watt-second is the energy equivalent to the power of one watt sustained for one second . While the watt-second is equivalent to the joule in both units and meaning, there are some contexts in which the term "watt-second" is used instead of "joule ...

Science Olympiad logo. Science Olympiad, sometimes abbreviated as Scioly, is an American team competition in which students compete in 23 events pertaining to various fields of science, including earth science, biology, chemistry, physics, and engineering. Over 7,800 middle school and high school teams from 50 U.S. states compete each year.
List of orders of magnitude for energy; Factor (joules) SI prefix Value Item 10 −34: 6.626 × 10 −34 J: Energy of a photon with a frequency of 1 hertz. [1]8 × 10 −34 J: Average kinetic energy of translational motion of a molecule at the lowest temperature reached (38 picokelvin [2] as of 2021)
Sunlight also drives most weather phenomena, save a few exceptions, like those generated by volcanic events for example. An example of a solar-mediated weather event is a hurricane, which occurs when large unstable areas of warm ocean, heated over months, suddenly give up some of their thermal energy to power a few days of violent air movement.

Latin and Greek letters are used in mathematics, science, engineering, and other areas where mathematical notation is used as symbols for constants, special functions, and also conventionally for variables representing certain quantities.
The International Junior Science Olympiad (IJSO) is an annual science competition for students aged 15 and under on December 31st of the competition year. It is one of the International Science Olympiads and an international academical competition that covers physics , chemistry and biology at the same time.
