SI Unit of Work (Joule).

The joule (symbol: J) is the unit of energy in the International System of Units (SI). It is named after the English physicist James Prescott Joule, who contributed to the study of thermodynamics and the concept of energy. The joule is defined as the amount of work done when a force of one newton is applied over a distance of one meter in the direction of the force. Mathematically, it can be expressed as: 1 J = 1 N × 1 m In addition to being a unit of energy, the joule is also used to measure other quantities, such as work, heat, and electrical energy. For example, if a machine does 100 joules of work, it means it has transferred 100 joules of energy to an object. Here are a few common energy values expressed in joules: 1 kilojoule (kJ) = 1,000 joules 1 megajoule (MJ) = 1,000,000 joules 1 gigajoule (GJ) = 1,000,000,000 joules The joule is a versatile unit that is widely used in various fields of science, including physics, chemistry, and engineering. It provides a standardized and convenient way to quantify and compare different forms of energy and energy transfers.
