Energy gives rise to weight when it is trapped in a system with zero momentum, where it can be weighed. The word energy derives from the Ancient Greek: ἐνέργεια, romanized: energeia, lit. The SI unit of energy is the joule, which is the energy transferred to an object by the work of moving it a distance of 1 metre against a force of 1 newton. 16

9 (where E At that time, according to theory, space expanded and the universe cooled too rapidly for hydrogen to completely fuse into heavier elements.
For other isotopes, the isotopic mass usually differs and is usually within 0.1 u of the mass number. Familiar examples of such processes include nuclear decay, in which energy is released that was originally "stored" in heavy isotopes (such as uranium and thorium), by nucleosynthesis, a process ultimately using the gravitational potential energy released from the gravitational collapse of supernovae, to store energy in the creation of these heavy elements before they were incorporated into the solar system and the Earth. The term atomic physics is often associated with nuclear power, due to the synonymous use of atomic and nuclear in standard English. All matter and objects contain a certain amount of energy, which varies according to their properties (position, mass, shape, speed, etc.) While the figures vary…, Following the March 2011 Fukushima accident, Japan shut down all 54 reactors in its nuclear fleet. Energy from the Sun is converted into growth factors by plants thanks to a process called photosynthesisProcess used by plants to fuel their growth.
