As such, the use of the newton-meter as a unit of work or energy is discouraged to avoid confusion regarding whether energy or torque is being expressed.We use cookies and similar tools that are necessary to enable you to make purchases, to enhance your shopping experiences and to provide our services, as detailed in our Cookie Notice. History/origin: The use of the newton-meter as a unit of work or energy is derived from the fact that the joule, the SI (International System of Units) unit of energy, is dimensionally equivalent to the newton-meter.Ĭurrent use: The newton-meter is more commonly used as a unit of torque rather than as a unit of work or energy. In this use, it is defined as the energy transferred to an object by a one newton force acting on that object in the direction of its motion over a distance of one meter. m) is sometimes used as a unit of work or energy and in this context is equal to the joule, the SI unit of energy.Newton-meterĭefinition: The newton-meter (N m should not be used to represent the joule whenever possible, to avoid confusion with torque.Even though the joule is algebraically equal to the N These units however, are different, and should be considered as such. m (Newton-meter), which is equivalent to the SI unit for torque.One of the dimensional representations of a joule is the N
Practical examples of energy measurement using joules include the energy required to lift objects, the energy released when objects fall, the heat required to raise temperature, and the kinetic energy of moving objects. He also discovered the relationship between heat and mechanical work, leading to the law of conservation of energy, and subsequently, the first law of thermodynamics.Ĭurrent use: As an SI derived unit, the joule is used within a variety of scientific contexts. Definition: The newton-meter (Nm) is sometimes used as a unit of work or energy and in this context is equal to the joule, the SI unit of energy. History/origin: The unit, joule, is named after James Prescott Joule, an English physicist and mathematician who helped develop the Kelvin scale. It has a number of representations both in SI base units as well as other SI units such that: It is also defined as the energy dissipated as heat when a 1 ampere electric current passes through a resistance of one ohm in the course of one second. It is defined as the energy transferred to an object when a one newton force is applied to the object in the direction of its motion through a distance of one meter.
Definition: A joule (symbol: J) is a derived unit of energy in the International System of Units (SI).
