It is equal to the energy transferred to or work done on an object when a force of one newton acts on that object in the direction of the force s motion through a distance of one metre 1 newton metre or n m. In physics energy is a scalar physical quantity that describes the amount of work that can be performed by a force an attribute of objects and systems that is subject to a conservation law.

Joule digunakan sebagai satuan usaha energi dan panas dan banyak digunakan dalam.
Physics joules. Different forms of energy include kinetic potential thermal gravitational sound light elastic and electromagnetic energy. It is a compound unit defined as 1 newton of force over a distance of 1 meter or as the kinetic energy of a 1 kilogram mass moving at one meter per second. The joule dʒ aʊ l dʒ uː l jowl jool.
Named for english physicist james prescott joule the joule j is one of the cornerstone units of the international metric system. The english physicist james prescott discovered that the amount of heat per second that develops in a current carrying conductor is proportional to the electrical resistance of the wire and the square of the current. Joule s law in electricity mathematical description of the rate at which resistance in a circuit converts electric energy into heat energy.
Named in honour of the english physicist james prescott joule it equals 10 7 ergs or approximately 0 7377 foot pounds. J is a derived unit of energy in the international system of units. Joule s law is a mathematical description of the rate at which resistance in a circuit converts electric energy into heat energy.
There are 4 19 joules in. Joules can also be converted from calories as calories are another unit of energy. It is equal to the work done by a force of one newton acting through one metre.
The joule is used as a unit of work energy and heat and is widely used in scientific applications. 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 alternatively it is the amount of work done on an object when a force of one newton acts in the direction of the object s motion over a distance of one meter 1 joule equal 1 newton meter or n m. It is also the energy dissipated as heat when an electric.
It is defined as the amount of work done on a body by a one newton force that moves the body over a distance of one meter. Joule unit of work or energy in the international system of units si. Joule is the unit of energy used by the international standard of units si.
The english physicist james prescott joule discovered in 1840 that the amount of heat per second that develops in a wire carrying a current is proportional. In science the joule is the unit of energy or work. Dinamai dari ahli fisika inggris james edward joule joule j adalah salah satu satuan dasar dari sistem metrik internasional.
