Kinetic Energy

Big ideas about kinetic energy

  • Kinetic Energy = heat, when heat is added kinetic energy increases, when heat is removed kinetic energy decreases
  • when kinetic energy increases, the particles increase in speed (move faster), start bumping into each other more often and hit each other harder, and create more space inbetween particles
  • when kinetic energy increases, the particles expand
  • when kinetic energy decreases, the particles contract
