The joule (/ˈdʒuːl/ or whiles /ˈdʒaʊl/), seembol J, is a derived unit o energy, wirk, or amoont o heat in the Internaitional Seestem o Units.[1] It is equal tae the energy expendit (or wirk duin) in applyin a force o ane newton throu a distance o ane metre (1 newton metre or N·m), or in passin an electric current o ane ampere throu a resistance o ane ohm for ane seicont. It is named efter the Inglis pheesicist James Prescott Joule (1818–1889).[2][3][4]
