Energy Transfers

Thermal Energy

Thermal Energy- all of the kinetic energy due to random motion of the particles that make up an object.

  • Particles move faster at higher temperatures.
  • Particles move slower at lower temperatures.
  • The faster the particles move the greater the kinetic energy.
  • Thermal Energy also depends on the number of particles.

(The sun is an example of thermal energy)

Chemical Energy

Chemical Energy- the energy of a compound that changes as its atoms are rearranged

  • This energy is a form of potential energy.
  • It depends on the position and arrangements of the atoms in a compound.
  • Our bodies use energy to perform task
(This is where the energy in food comes from)

Sound Energy

Sound Energy- Is caused by an object's vibrations.

  • Sound produces a low level of energy compared to other types of energy.
  • Sound energy isn't really used for electricity.
  • The measurement of sound energy is related to it's pressure and intensity.
  • Sound travels faster than a liquid through the air.

Nuclear Energy

Nuclear Energy- the energy that comes from changes in the nucleus of the atoms.

  • The energy given off by the sun comes from nuclear energy.
  • Fusion gives off a huge amount of energy.
Fusion- the reaction in which two atoms of hydrogen combine together to form an atom
  • Fission is used to generate electrical energy at nuclear power plants.
Fission- The splitting of heaver nuclei in to two smaller nuclei.

(Nuclear Power Plant)

Light Energy

Light Energy-Is produced by the vibrations of electrically charged particles

  • Light energy is always moving so it can not be stored.
  • The speed of light changes when it goes through different objects.
  • Every year lighting kills 1,000 people.
(lightning is an example of light energy)
