Thermal energy

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

- particles move faster at at higher temperatures than lower temperatures

- faster the particles move the faster the kinetic energy and the greater the objects thermal energy

- joule is the unit used to measure thermal energy

- thermal energy can be transferred 3 ways: convection, conduction, radiation

This picture explains thermal energy because the hotter the particles the faster they move

Chemical energy

Chemical energy is the energy of a compound that changes as its atom are rearranged

-form of potential energy because it depends on the position and arrangements of the atoms in a compound

-is released as a chemical reaction

-once chemical energy is released from a substance, that substance is transformed into a totally different substance

Your body converts chemical energy into energy for your body

Electrical Energy

Electric energy is the energy of moving electrons

- electrons are the negatively charged particles of atoms

- the electric energy of moving electrons is used to do work

-the electrical energy you use in your home comes from power plants

-electrons in wires can transfer energy to different parts inside a device

This picture explains electrical energy because the plug in is converting it's energy into the cords which is giving energy to whatever object it's attached to

Sound Energy

Sound energy is the movement of energy through substances

-sound is produced when a force causes an object or substance to vibrate

-energy is transferred through a substance wave

-the sound waves mover through the air

The picture of a boom box is representing sound energy because the the sound waves are coming out of the speaker and bouncing off every object in the room making it possible for you to hear

Light Energy

Light energy is produced by the vibrations of electrically charged particles

-keeps us warm and lets us see the world

-not all light energy can be seen

-light vibrations can cause energy to be transmitted

this light bulb is producing light for someone to see

Nuclear Energy

Nuclear energy is energy that comes from changes in the nucleus of an atom

-Atoms store a lot of potential energy because of the positions of the particles in the nucleus of the atom

-The energy given off by the sun comes from nuclear energy

-Without nuclear energy from the sun, life on earth would't be possible

This nuclear power plant is full of atoms with potential energy
