top left- fossil fuel. resources. top right- kinetic theory, solid, liquid, or gas, solar energy and others.bottom right, all the energies like sound energy,energy transformation.bottom left, conductors, insulators, potential energy and kinetic, thermal energy, chemical
potential energy- energy that an object has due to its position, condition, or chemical composition. an example a skater has kinetic energy as he moves down the ramp. potential energy due to its position on the ramp
-
sound energy- kinetic energy caused by the vibration of particles in a medium such as steel, water, and air. example is a guitar
-
-
electromagnetic energy- transmitted through space in the form of electromagnetic waves- the waves include visible light, x-rays, microwaves
law of conversation of energy- states that energy cannot be created nor destroyed it can only change from
energy transformation- takes place when energy changes from one form to another form. examples are when you rub your hands together
-
chemical energy- a form of potential energy. the amount of chemical energy in a molecule depends on the kinds of atoms and their arrangement
Thermal energy- kinetic energy of its particles. particles move faster at higher temperature. faster the molecules more thermal energy
difference between thermal energy and temperature-temperature is related to average kinetic energy of particles and thermal energy is total kinetic energy of all particles

-
conductors- material that transfers heat very well- examples- metal , metal pots
insulators- material that is poor conductor of heat, examples- wood paper,plastic, plastic foam
kinetic theory of matter- states that all of the particles that make up matter are constantly in motion
-
-
particles in a solid such as concrete are not free to move around very much.they vibrate back and fourth in the same position and are held tightly together by forces of attraction
-
in a gas such as the air around you, particles are fa apart and move around at high speeds. particles collide with one another but other wise they do not interact much
-
-
radiation- transfer of energy by electromagnetic waves- examples- visible light, microwaves, infrared light
-

-
renewable resource- energy source that can be easily reproduced or replaced by nature - example- trees
nonrenewable resource- energy source that cannot be produced grown or restored - examples energy rich minerals, coal, petroleum , and natural gas , gasoline
