The SI unit for work in physics is Joule (J).A joule in base units 1 kg.m2.s-2.
J. A. Joule has written:
'Heterocyclic chemistry' -- subject(s): Heterocyclic chemistry
The joule is the SI unit for energy.
The unit of power is the watt (W), which is equal to one joule per second.
Both the joule and the watt are derived units. (They are both surnames so their symbols are always capitalised: J and W.)
For the pure physics geeks:
a joule is m2 kg s-2 and
a watt is m2 kg s-3
The SI unit for Energy is the same unit used for work, which is the Joule.
The defition of a Joule is:
J = N * m = kg*m^2/s^2
Where:
kg is kilogram
m is meter
s is second
N is Newton
J is Joule
1 joule = 1 N × m (1 newton-metro) = 1 W × s (watts-segundo)
