Standard units of joules
WebbNamed for English physicist James Prescott Joule, the joule (J) is one of the cornerstone units of the International metric system. The joule is used as a unit of work, energy, and heat, and is widely used in scientific applications. If... WebbUnlike velocity, acceleration, force, and momentum, the kinetic energy of an object is completely described by magnitude alone. Like work and potential energy, the standard metric unit of measurement for kinetic energy is the Joule. As might be implied by the above equation, 1 Joule is equivalent to 1 kg* (m/s)^2. 1 Joule = 1 kg • m2/s2.
