Medical Definition of joule. : a unit of work or energy equal to the work done by a force of one newton acting through a distance of one meter.
The SI prefix tera represents a factor of 10 12, or in exponential notation, 1E12. So 1 terajoule = 10 12 joules. The definition of a joule is as follows: The joule (symbol J, also called newton meter, watt second, or coulomb volt) is the SI unit of energy and work.The unit is pronounced to rhyme with tool, and is named in honor of the physicist James Prescott Joule (1818-1889).he definition of a joule is as follows: The joule (symbol J, also called newton meter, watt second, or coulomb volt) is the SI unit of energy and work.
