Document Summary
Energy is defined as the capacity for doing work. Einstein suggested that energy and matter are related to each other at the atomic level. Scientists could extract the atomic energy found in matter beginning in the 1940s via a process called nuclear fission. In 1998, energy was successfully transferred into matter. Energy and matter have associations to each other at much larger scales of nature. For example, plants convert solar radiation into food and energy. Basic energy: kinetic energy, potential energy, heat energy, electricity energy, sound energy, chemical energy, magnetic energy. A newton is equal to the force needed to accelerate a mass weighing one. 1 newton over 1 meter = 1 joule. Calorie = amount of heat required to raise 1 gram of pure water from 14. 5 to 15. 5 degrees celsius at standard atmospheric pressure. Btu - british thermal unit is the amount of energy required to raise the temperature of one pound of water 1 fahrenheit.
