What are energy and work? (article) | Khan Academy
The definition of work, W, is below: W = F ⋅ Δ x. The work we need to do to burn the energy in the candy bar is E = 280 cal ⋅ 4184 J / cal = 1.17 MJ . Therefore, the distance, Δ x, we need to move the box through is: W = F
Laboratory Exercises for Physics 101
Definition: (Density of a body) = (body''s mass)/(body''s volume) or D = M / V. The density of a substance is independent of the shape or the particular amount of that substance. For example, the density of a small gold ring and the density of a large gold brick should be the same number, i.e., the density of gold.

Energy storage
OverviewHistoryMethodsApplicationsUse casesCapacityEconomicsResearch
Energy storage is the capture of energy produced at one time for use at a later time to reduce imbalances between energy demand and energy production. A device that stores energy is generally called an accumulator or battery. Energy comes in multiple forms including radiation, chemical, gravitational potential, electrical potential, electricity, elevated temperature, latent heat and kinetic. Ene
