The joule (/ dʒ uː l / JOOL, or / dʒ aʊ l / JOWL; symbol: J) is the unit of energy in the International System of Units (SI). [1] It is equal to the amount of work done when a force of one newton displaces a mass through a distance of one metre in the direction of that force.
7 mar 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).
7 sie 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.
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.
Joule's apparatus for measuring the mechanical equivalent of heat. A descending weight attached to a string causes a paddle immersed in water to rotate. In the International System of Units (SI), the unit of energy is the joule.
11 maj 2021 · One joule is equivalent to the energy expended, or work done, by a force of one newton accelerating a one-kilogram mass through a distance of one meter in one second. Essentially, a one-newton force, acting on a one-kilogram mass, will accelerate that 1-kg mass through one meter in one second.
Definition. Joules are the standard unit of energy in the International System of Units (SI), representing the amount of work done when a force of one newton is applied over a distance of one meter.
