SOL PS 6 • Energy • Potential energy Gravitational potential energy Kinetic energy • The ability to do work. • Energy stored based on position or chemical composition. • Weight X height • Energy of motion. • Depends on the mass & velocity of the moving object.

• Forms of energy • • Light Heat Chemical Electrical Mechanical Nuclear Sound

• Light • Heat/Thermal • Produced by the vibrations of electrically charged particles. • Transfers energy without a medium. • All of the kinetic energy due to random motion of the particles. • Depends on the number of particles as well as the temperature.

• Chemical • Electrical • The energy of a compound that changes as its atoms are rearranged. • A form of potential energy. • The energy of moving electrons.

• Mechanical • Total energy of motion & position of an object. • ME=potential + kinetic • Nuclear • Energy that comes from changes in the nucleus of an atom. • Fission-splitting of an atom. (Power plants) • Fusion-joining of nuclei to make a larger nucleus. (Sunlight & heat)

• Sound • Energy Transformations • A vibrating object transmits energy through the air around it. • Travels as a longitudinal wave. • Energy can be transformed from one type to another. • Some of the energy is lost to the environment as heat.
