the energy en ingles conocimiento echo por alberto fernandez

2. If we look around we can see how the
wind moves the leaves of the trees as
the sun warms the objects that were
previously cold
There are five ways to classify
energy:
Energy Kinetics
light energy
thermal energy
sound energy
chemical energy

3. forms of energy
• Energy Kinetics : or of the movement, as the
who have bodies in motion.
• light energy : like the Sun or light bulbs,
which emit light
• thermal energy : as the bodies that are hot.
• sound energy :as the of musical instruments
when they emit sounds
• chemical energy : as that have food or
batteries

4. When entering a car that has been parked in
the Sun, we noticed your indoor air is so hot
that it is stifling. is it due to that light energy
from the Sun has been transformed into
thermal .on energy both, a form of energy
can be transformed into another form of
energy

5. the appliances most used in house, such as the TV, the fridge or
hair dryer electricity-powered
electricity is a form of energy useful:
.easily transported through cables
. It is transformed into other types of energy
thermal energy in a heating or energy kinetics in
a fan

6. energy source most used
• fuels like coal gas and oil
• Coal : obtained from mines
• the natural gas : is located in underground deposits
• the oil : also is extracted by Wells
• the water : water in motion has kinetic energy or
movement
• the wind : It has kinetic energy. for many years it was
used in windmills

7. energy source most used
Coal :
the natural gas
the oil
the water
the wind :

8. other energy sources
• The sun : has thermal energy and light energy
• rocks of volcanic areas: stored thermal
energy
• the swell of the sea and tides: the solo and
the rises and drops cde tides have kinetic
energy

9. non-renewable and renewable sources
• non-renewable sources: as oil, coal or natural gas
there is on Earth in limited quantities
• sources energies: as the Sun or wind. They
regenerate as they are consuming or exist in such
large quantities that they are considered
inexhaustible
