Joule
Definition: The joule (symbol: J) is the SI derived unit of energy. It is defined as the energy transferred to (or work done on) an object when a force of one newton acts on that object in the direction of its motion through a distance of one metre (1 newton metre or N⋅m).
History/origin: Named after James Prescott Joule, an English physicist. Joule experimentally determined the mechanical equivalent of heat.
Current use: Used universally in science and engineering to quantify energy, work, and heat. Examples include kinetic energy, potential energy, and heat content of materials.
Watt-hour
Definition: A watt-hour (symbol Wh) is a unit of energy equal to one watt of power sustained for one hour. It is commonly used to measure electrical energy consumption.
History/origin: The watt-hour is derived from the watt, the SI unit of power, and the hour, a unit of time. It was developed alongside the increasing use of electricity in the late 19th and early 20th centuries.
Current use: Watt-hours are commonly used to measure the energy capacity of batteries, the energy consumption of household appliances, and the amount of electricity generated or consumed by power plants and consumers.
