The megajoule is approximately the kinetic energy of a one megagram (tonne) vehicle moving at 161 km/h (100 mph). The energy required to heat 10 L of liquid water at constant pressure from 0 °C (32 °F) to 100 °C (212 °F) is approximately 4.2 MJ. One kilowatt-hour of electricity is 3.6 megajoules. Gigajoule Meer weergeven 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 … Meer weergeven 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 … Meer weergeven 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 … Meer weergeven 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 … Meer weergeven 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 … Meer weergeven 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 Meer weergeven 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) Meer weergeven WebKinetic energy can’t be negative, although the change in kinetic energy.
