SUMMARY
The unit of energy, the Joule, is named after James Prescott Joule and is defined as 1 kg·(m/s)². The Joule was introduced as part of the International System of Units (SI) to standardize measurements of energy. The definition of energy in terms of mass and velocity, represented as kg·(m/s)², reflects the principles of classical mechanics, particularly the concept of vis viva. Historical context indicates that the formal adoption of the Joule occurred during the establishment of the SI system, which aimed to unify various measurement standards.
