Principles of EnergyChapter 1
What is Energy?• Energy is defined as the ability to
produce change or do work.
• Light
• Sound• Motion
• Technology
• Heat
• Growth
Forms of Energy
• Potential Energy: the energy that a piece of matter has because of its position or nature or because of the arrangement of parts.
• Kinetic Energy: the energy of an object associated with its motion.
Potential Energy
• Potential Energy is stored energy and the energy of position, or gravitational energy. There are several forms of potential energy, including:– Chemical energy– Stored Mechanical Energy– Gravitational Energy

Conservation of Energy
• A principle in physics: the total energy of an isolated system remains constant irrespective of whatever internal changes may take place with energy disappearing in one form and reappearing in another.
