Named in honour of the english physicist james prescott joule it equals 10 7 ergs or approximately 0 7377 foot pounds. Substituting the values in the equation we get q 10 2 300 30 60 54000000 j or 54 mj.

Physics joules formula. If you want your answer to be in joules always make sure to use standard scientific units. J is a derived unit of energy in the international system of units. It is also the energy dissipated as heat when an electric.
In science the joule is the unit of energy or work. 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.

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 is used as a unit of work energy and heat and is widely used in scientific applications. Joules can also be converted from calories as calories are another unit of energy.
There are 4 19 joules in. The foot pound or the british thermal unit are still used in some fields but they have no place in your physics homework.
