NettetIt is defined Table: Units and dimensions of some physical quantities by taking the fixed numerical value of the Quantity SI Unit Dimension Boltzmann constant k to be 1.380649×10–23 Density kg/m3 M/L3 when expressed in the unit J K–1, which is equal to kg m2 s–2 k–1, where the kilogram, Force newton (N) ML/T2 metre and second are … 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 – … 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 newton-metre, which works out algebraically to have the same dimensions as … 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 … 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. 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 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 Se mer
