Law of Conservation of Energy Energy cannot be created or
destroyed.
Slide 5
There are two states of energy or types of energy. Potential
and kinetic.
Slide 6
Potential Potential is stored energy
Slide 7
Kinetic Kinetic is the energy of motion.
Slide 8
There are five main forms of energy. Chemical Mechanical
Electromagnetic Heat (thermal) Nuclear
Slide 9
Chemical Energy Energy that is available for release from
chemical reactions.
Slide 10
Mechanical Energy Energy due to a objects motion (kinetic) or
position (potential).
Slide 11
Electromagnetic oLight energy o Includes energy from gamma
rays, xrays, ultraviolet rays, visible light, infrared rays,
microwave and radio bands oMoving electric charges
Slide 12
Heat or Thermal Internal motion of atoms. The heat energy of an
object determines how active its atoms are.
Slide 13
Nuclear Nuclear energy is the energy stored in the nucleus of
an atom and can be broken into: fusion (energy of the sun which is
the combing of two or more nuclei) and fission(the splitting of an
atom like in a nuclear reactor).
Slide 14
Energy Transfer Chemical Electrical Sound (mechanical) Light
(Electromagnetic) Thermal Mechanical
Slide 15
There are three types of (energy) heat transfer. Convection
Conduction Radiation
Slide 16
Convection Convection is the transfer of heat energy in a gas
or liquid by movement of currents due to changes in density.
Slide 17
Conduction is the transfer of energy through matter from
particle to particle.
Slide 18
Radiation Allows heat to be transferred through wave
energy.
Slide 19
Slide 20
Renewable Renewable resources are those resources that can be
replaced as they are used up. Some examples include: soil air water
wood sunlight
Slide 21
Non-Renewable Nonrenewable resource are those natural resources
that cannot be replaced once they are used up. Some examples
include: oil coal gas uranium
