Also the related concept of work, which can be thought of as the transfer of … 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 kg mass at 1 m/s through a distance of 1 m.The kinetic energy of a 2 kg mass travelling at 1 m/s, or a 1 kg mass travelling at 1.41 m/s.The energy required to lift a medium-sized … Se mer 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 … Se mer 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 Landauer limit. Nanojoule 160 nanojoule is about the kinetic energy of a flying mosquito. … Se mer 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 Se mer 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 … Se mer 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: Se mer 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. Wilhelm Siemens, in his inauguration speech … Se mer 1 joule is equal to (approximately unless otherwise stated): • 10 erg (exactly) • 6.24150974×10 eV • 0.2390 cal (gram calories) • 2.390×10 kcal (food calories) Se mer
