Derived unit of joule
Did you know?
WebA joule is 1 newton times 1 meter. The newton, in turn, is the force required to acceleration a mass of 1 kilogram, by 1 meter/second squared. Thus, the joule is ultimately derived … SI derived units are units of measurement derived from the seven base units specified by the International System of Units (SI). They can be expressed as a product (or ratio) of one or more of the base units, possibly scaled by an appropriate power of exponentiation (see: Buckingham π theorem). Some are dimensionless, as when the units cancel out in ratios of like quantities. The SI has special names for 22 of these derived units (for example, hertz, the SI unit of measur…
