what is a terajoule
The terajoule (TJ) is equal to one trillion (10 12) joules. About 63 TJ of energy was released by the atomic bomb that exploded over Hiroshima. The International Space Station, with a mass of approximately 450 megagrams and orbital velocity of 7.7 km/s, has a kinetic energy of roughly 13 TJ.orque and energy are related to each other using the equation. where E is the energy, Ï is the torque, and Î¸ is the angle moved (in radians). Since radians are dimensionless, it follows that torque and energy have the same dimensions.
