One joule is equal to the amount of work done when a force of one newton displaces a body through a distance of one metre in the direction of that force. It is also the energy dissipated as heat when an electric current of one ampere passes …

Aug 7, 2024 · What is a Joule? A Joule is a unit of energy in the International System of Units (SI). It is defined as the amount of work done when a force of one newton is applied over a distance of one meter. In simpler terms, a Joule represents the energy required to perform a specific action, such as lifting a small apple one meter up in the air.

Mar 7, 2019 · The joule (symbol: J) is the basic SI unit of energy. A joule is equal to the kinetic energy of a kilogram mass moving at the speed of one meter per second (one joule is a kg⋅m 2 ⋅s −2).

Feb 28, 2025 · Named for English physicist James Prescott Joule, the joule (J) is one of the cornerstone units of the International metric system. The joule is used as a unit of work, energy, and heat, and is widely used in scientific applications.

joule, unit of work or energy in the International System of Units (SI); it is equal to the work done by a force of one newton acting through one metre. Named in honour of the English physicist James Prescott Joule, it equals 10 7 ergs, or approximately 0.7377 foot-pounds.

A Joule (J) (/ ˈ dʒ aʊ l / or sometimes / ˈ dʒ uː l /) is a unit in the SI system named after English physicist James Prescott Joule.

Nov 17, 2023 · Joule (J) is the standard unit of measurement for energy in the International System of Units (SI). It is defined as the energy required to move an object one meter in the direction of the force of one Newton. The joule is used in different fields, including physics, engineering, and chemistry.

May 10, 2023 · 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.

Aug 22, 2024 · What is a joule class 11 physics? Joule is the SI unit of work or energy. One joule is defined as the amount of work done when a force of one newton acts on an object in the direction of its motion through a distance of one metre.

Apr 12, 2022 · The SI unit for Energy is the joule, usually abbreviated J. One joule is equal to one kilogram meter squared per second squared: \(\ 1 \mathrm{~J}=1 \frac{\mathrm{kg} \mathrm{m}^{2}}{\mathrm{~s}^{2}}\)
