Energy and Matter • Chapter 2 Section 4
Energy is never created or destroyed! • It is TRANSFORMED • (Changed from one form to another)
Forms of Energy • Kinetic • Potential • Chemical • Electromagnetic • electrical • thermal energy
Kinetic Energy • Energy of matter in Motion • Kinetic energy of particles contributes to • the thermal energy of a substance
Potential Energy • Energy an object has because of its position.
Chemical Energy • Internal energy stored in the chemical bonds between atoms. it is a form of potential energy. Muscles use the stored chemical energy of food we eat and convert that to heat and energy of motion.
Electromagnetic Energy • Energy that travels through space as waves.
Electrical Energy • Energy of electrically charged particles moving from one place to another. • Electrons move from one atom to another in many chemical changes.
Transforming Energy Other forms of energy may also be changed to chemical energy. • During a chemical change, chemical energy may be changed to other forms of energy.
