What are energy and work? (article) | Khan Academy
https://www.khanacademy.org/science/physics/work-and-energy/work-and-energy-tutorial/a/what-is-work
WEBHow do we measure energy and work? The standard unit used to measure energy and work done in physics is the joule, which has the symbol J. In mechanics, 1 joule is the energy transferred when a force of 1 Newton is applied to an object and moves it through a distance of 1 meter. Another unit of energy you may have come across is the Calorie.

WEBOne way to define energy is the ability to do work, where work equals force, measured in newtons, times the distance, measured in meters, an object is moved in the direction of the force. Scientists use the joule to measure work. One joule is equal to the work done by a force of one newton to move an object one meter in the direction of the force.
