Joules Formula Physics ~ Indeed recently has been hunted by users around us, perhaps one of you. People are now accustomed to using the internet in gadgets to view image and video information for inspiration, and according to the title of this post I will discuss about Joules Formula Physics. Current location physics formulas electromagnetism joule s law. You need to know the mass of the object as well as the velocity at which it is traveling. Don t forget to try our free app agile log which helps you track your time spent on various projects and tasks try it now. In science the joule is the unit of energy or work. Joule s law is given by. 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 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. Named in honour of the english physicist james prescott joule it equals 10 7 ergs or approximately 0 7377 foot pounds. It is equal to the work done by a force of one newton acting through one metre. There are 4 19 joules in every calorie. 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. The joule dʒ aʊ l dʒ uː l jowl jool. He determined that the heat evolved per second is equivalent to the electric power absorbed or the power loss. For example you could work out the mass of a bowling ball and then drop it off a building to work out what its velocity is. Watts joules time. Joules can also be converted from calories as calories are another unit of energy. Here the unit joule is equivalent to a unit amount of watt for a unit second. Joule s law is a mathematical description of the rate at which resistance in a circuit converts electric energy into heat energy. The joule is used as a unit of work energy and heat and is widely used in scientific applications. The foot pound or the british thermal unit are still used in some fields but they have no place in your physics homework.
Current location physics formulas electromagnetism joule s law. The joule dʒ aʊ l dʒ uː l jowl jool. Named in honour of the english physicist james prescott joule it equals 10 7 ergs or approximately 0 7377 foot pounds.

Joule s law is a mathematical description of the rate at which resistance in a circuit converts electric energy into heat energy.
So our expression for work the energy used is. Joule unit of work or energy in the international system of units si. It is also the energy dissipated as heat when an electric. Watts joules time.
