Mar 18, 2024 · 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 is the SI base unit for energy. It is equal to 1kg⋅m2 s2 1 k g ⋅ m 2 s 2. [1] . In physical terms, lifting an apple one meter takes 1 joule of energy. This should not be confused with a watt which is a unit of power and a rate of how fast energy is used.
6 days ago · 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. J = kg.m².s⁻². = N.m.
A joule ( / ˈdʒaʊl / or sometimes / ˈdʒuːl /) is a unit in the SI system. It measures energy; usually in scientific or electrical appliances . It is named after James Prescott Joule. A joule refers to the amount of energy transferred to an object when a force of 1 newton is applied on it over a distance of 1 metre (1J = 1N × 1m).
In slightly more fundamental terms, 1 joule is equal to 1 newton metre and, in terms of SI base units. An energy unit that is used in atomic physics, particle physics and high energy physics is the electronvolt (eV). One eV is equivalent to 1.602 176 634 × 10−19 J. [2]
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.
One joule is equal to the work done by a force of one newton to move an object one meter in the direction of the force. To use a real-life example, gravity exerts about 1 newton of force on the average apple. To raise an apple one meter in the air, you must use one joule of kinetic energy.
