In terms of SI base units and in terms of SI derived units with special names, the joule is defined as One joule can also be defined by any of the following: The work required to move an electric charge of one coulomb through an electrical potential difference of one volt, or one coulomb-volt (C⋅V). This relationship can be … See more The joule is the unit of energy in the International System of Units (SI). It is equal to the amount of work done when a force of 1 newton displaces a mass through a distance of 1 metre in the direction of the force applied. It is … See more Zeptojoule 160 zeptojoule is about one electronvolt. The minimal energy needed to change a bit at around room temperature – approximately 2.75 zJ – is given by the … See more In mechanics, the concept of force (in some direction) has a close analogue in the concept of torque (about some angle): A result of this similarity is that the SI unit for torque is the See more The cgs system had been declared official in 1881, at the first International Electrical Congress. The erg was adopted as its unit of energy in 1882. See more One joule represents (approximately): • The amount of electricity required to run a 1 W device for 1 s. • The energy required to accelerate a 1 See more 1 joule is equal to (approximately unless otherwise stated): • 10 erg (exactly) • 6.24150974×10 eV • 0.2390 cal (gram calories) See more A watt-second (symbol W s or W⋅s) is a derived unit of energy equivalent to the joule. 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, … See more WebMay 6, 2024 · 1 Joule = 1 Kgm^2/s^2 a complex unit derived from the definition of work. The definition of work is a force acting over a distance. => Work = Force x Distance = F x d From Newton's 2nd Law of Motion, Force = Mass x Acceleration => F = m x a Substituting m x a …
