What is Energy (E)?•Work– Ability to move something = application of force across a distance•Energy -The capacity or ability to do WORK, e.g., heat, sunlight, sound, electricity, chemical bonds, movementPOTENTIAL Energy- " stored " and not presently being used; results from the relative position of matter (as opposed to matter in motion)e.g., biomass, coal, oil, natural gasKINETIC Energy- energy associated with a body in motione.g., heat, γrays, sunlight, sound, electricity, mvmt
