WebThe equation relating matter and energy is E=mc^2, where E is energy, m is mass, and c is the speed of light. Therefore: E = 3g x (3x10^8 m/s)^2. E = 3g x 9x10^16 m^2/s^2. E = 27x10^16 g x m^2/s^2. E = 27x10^13 J. Therefore, approximately 27x10^13 joules of energy would be released if three grams of matter were converted to energy. WebThe SI unit of work is joule (J).
