Wikipedia Definition The joule jawl jool.
Units of joule. Joule is a standard unit of measurement for work or energy used in electricity mechanics thermal energy and general scientific applications. It is equal to the energy transferred to an object when a force of one newton acts on that object in the direction of the forces motion through a distance of one metre. The unit of energy in SISymbol J.
A unit of electrical energy equal to the work done when a current of one ampere is passed through a resistance of one ohm for one second. This definition causes the SI unit for energy is the same as the unit of work the joule JJoule is a derived unit of energy and it is named in honor of James Prescott Joule and his experiments on the mechanical equivalent of heat. Usually in scientific or electrical appliances.
A joule ˈ dʒ aʊ l or sometimes ˈ dʒ uː l is a unit in the SI system. Expressed in terms of SI base units it i. A unit of energy or work done 2.
The International System unit of electrical mechanical and thermal energy. The joule is a derived unit of energy in the International System of Units. Convert between joules or megajoules and other major units of energy.
The joule J is the SI unit of energy and is named after English physicist James Prescott Joule 18181889. If we go back to the equation for kinetic energy written above we can put units in kg for mass and m2 s2 m 2 s 2 for velocity squared. Then in terms of SI base units a joule is equal to a kilogram times meter squared divided by a.
J is the basic SI unit of energyA joule is equal to the kinetic energy of a kilogram mass moving at the speed of one meter per second one joule is a kgm 2 s 2Alternatively it is the amount of work done on an object when a force of one newton acts in the direction of the objects motion over a distance of one meter 1 joule equal 1 newton meter or Nm. A force of 1 newton acting through a distance of 1 meter. A unit of energy or work done 3.
