  3. Poynting vector - Wikipedia

    en.wikipedia.org/wiki/Poynting_vector

    This expression is often called the Abraham form and is the most widely used. [7] The Poynting vector is usually denoted by S or N . In simple terms, the Poynting vector S depicts the direction and rate of transfer of energy, that is power , due to electromagnetic fields in a region of space that may or may not be empty.

  5. Power of 10 - Wikipedia

    en.wikipedia.org/wiki/Power_of_10

    Visualisation of powers of 10 from one to 1 trillion. In mathematics, a power of 10 is any of the integer powers of the number ten; in other words, ten multiplied by itself a certain number of times (when the power is a positive integer). By definition, the number one is a power (the zeroth power) of ten. The first few non-negative powers of ...

    In 1864, Rudolf Clausius proposed the Greek word ἐργον (ergon) for the unit of energy, work and heat. [2] [3] In 1873, a committee of the British Association for the Advancement of Science, including British physicists James Clerk Maxwell and William Thomson recommended the general adoption of the centimetre, the gramme, and the second as fundamental units (C.G.S. System of Units).

  7. Orders of magnitude (length) - Wikipedia

    en.wikipedia.org/wiki/Orders_of_magnitude_(length)

    The centimetre (SI symbol: cm) is a unit of length in the metric system equal to 102 metres (⁠ 1 / 100 ⁠ m = 0.01 m). To help compare different orders of magnitude, this section lists lengths between 102 m and 10 −1 m (1 cm and 1 dm). 1 cm – 10 millimeters; 1 cm – 0.39 inches; 1 cm – edge of a square of area 1 cm 2

  9. Power (physics) - Wikipedia

    en.wikipedia.org/wiki/Power_(physics)

    The output power of a motor is the product of the torque that the motor generates and the angular velocity of its output shaft. Likewise, the power dissipated in an electrical element of a circuit is the product of the current flowing through the element and of the voltage across the element. [1] [2]
