2. LIGHT ENERGY
Most of the ligh on earth come frome the
sun.Light can be natural or artificial examples:
bulbs and torches.
Light travels very fast.is more faster fron of
energy. Travels at 300 000 kilometers per
second.
Light always travel in a strainght line.
Line can be absorbed,reflected or refracted.
3. CHEMICAL ENERGY
Chemical energy is relased when a chemical
reaction occurs. Chemical reactions occurs
between the pretol and oxygen. BETERIES AND
FOOD are surces of chemical energy too.
4. SOUND ENERGY
Sound is a vibration and can travel in any
directions from the source. Vibrating objet
transmit into the airand reach our ear. We
percive large vibrations as lound sounds as
soft sounds.
Sound can travel very quickly, but not as light
5. KINETIC ENERGY
All moving things ,from large planets to tity
atoms ,have kinetic energy is producer
through motion or movement . The havier an
object is, and the faster it moves.examples:
car,a windsurfer or your bike.
6. ELECTRICAL ENERGY
Electrical energy is user to power
machines. We can transformed it
into ligth,sound,heat and
movement.
The energy electricity comes from
diferent sources is still produced by
burning fossil fuels,sunligth,whind,
water, biomas,nuclear power
stations.
7. ENERGY SURCES
SOLAR ENERGY
This energy is renewable and
doesn”t pollute, howere
solar panels can only be used
in sunny
WHIND ENERGY
This enery is clean and
renewable but wind
turbines only work in
whindy places. They can
also damage habitats and
kill birds.
8. .
BIOMASS
Biomass is organic material
derived from living things
such wood dried vegetation
of food waste. This produce
steam, whit turns a turbine
and generates electricity
THIS ARE BIOMASS PELLETS
GEOTHERMAL ENERGY
Geotermal energía is heat
Producer By the
decomposition of
undengroud radio active
substancies. Geothermal
energy is renewable and
isn”t contaminatig, but it”s
limited to certain
geographic areas
