The SI (metric) unit of work is the joule. The roule is also the base unit a energy,v work is just a variant of energy. One joule is the energy used (or work done) moving a force of one newton a...
It is a derived unit. It measure distance traveled per unit of time. For example meter per second or m/s. Speed or velocity as it is sometimes called is derived from the units for distance and time.
The Joule is the unit of energy in the SI system. The most fundamental definition of the Joule is the energy (or work done) in moving 1 meter against a force of 1 Newton.
