## Joule – wikipedia gas x reviews ratings

A result of this similarity is that the SI unit for torque is the **newton metre**, which works out algebraically to have the same dimensions as the joule. But they are not interchangeable. The CGPM has given the unit of energy the name joule, but has not given the unit of torque any special name, hence it is simply the **newton metre** (N⋅m) – a compound name derived from its constituent parts. [5] The use of newton metres for torque and joules for energy is helpful to avoid misunderstandings and miscommunications. [5]

The distinction may be seen also in the fact that energy is a scalar – the dot product of a vector force and a vector displacement. By contrast, torque is a vector – the cross product of a distance vector and a **force vector**. Torque and energy are related to one another by the equation E = τ θ , {\displaystyle E=\tau \theta \ ,}

Since the joule is also a watt-second and the common unit for electricity sales to homes is the kW⋅h (kilowatt-hour), a kW⋅h is thus 1000 W × 3600 s = 3.6 MJ (megajoules). Multiples [ edit ] For additional examples, see: Orders of magnitude (energy) SI multiples for joule (J) Submultiples

The terajoule (TJ) is equal to one trillion (10 12) joules; or about 0.278 GWh (which is often used in energy tables). About 63 TJ of energy was released by the atomic bomb that exploded over Hiroshima. [14] The International Space Station, with a mass of approximately 450 megagrams and orbital velocity of 7.7 km/s, [15] has a kinetic energy of roughly 13 TJ. In 2017 Hurricane Irma was estimated to have a peak wind energy of 112 TJ. [16] [17] Petajoule [ edit ]

The exajoule (EJ) is equal to one quintillion (10 18) joules. The 2011 Tōhoku earthquake and tsunami in Japan had 1.41 EJ of energy according to its rating of 9.0 on the moment magnitude scale. Yearly U.S. energy consumption amounts to roughly 94 EJ. Zettajoule [ edit ]

The yottajoule (YJ) is equal to one septillion (10 24) joules. This is approximately the amount of energy required to heat all the water on Earth by 1 °C. The thermal output of the Sun is approximately 400 YJ per second. Conversions [ edit ]
