Lesson 1.4
Energy & Matter       

Key Concepts
  • What are some forms of energy that are related to changes in matter?
  • How is chemical energy related to chemical change?
Vocabulary
  • kinetic energy
  • potential energy
  • chemical energy
  • electromagnetic energy
  • electrical energy
  • electrodes
Energy
  • Like matter, energy cannot be created or destroyed in chemical reactions.
  • However, energy does change from one form to another.
 
Forms of Energy
  • Forms of energy related to changes in matter may include kinetic, potential, chemical, electromagnetic, electrical, and thermal energy.
Kinetic Energy
  • Kinetic energy is the energy of motion.
  • A rolling ball has kinetic energy.
Kinetic Energy of Atoms
  • Atoms, the smallest particles of matter, have kinetic energy because they are always moving.
Potential Energy
  • Potential energy is the energy of an object because of its position.
  • You can think of this energy as energy stored for later use.
Energy Transfer
  • A stretched rubber band has potential energy.
  • When the rubber band is released, its potential energy becomes kinetic energy.
