5. SOUND
*Sound is a vibration and can
travel in any direction from the
source.
*Vibrating objects transmit
these vibratons into the air.
*Large vibrations -> loud sound
*Small vibratons-> soft sounds
*Sound can travel
through gases, liguids
ando solids, even if they
are opaque
6. CHEMICAL
Chemical energy is
released when a
chemical reacton occurs
A Chemical reaction
occurs between the
petrol and oxigen
This chemical energy is then
transformed into kinetic energy
7. KINETIC
All moving things,
from large planets
to tiny atoms, have
kinetic energy.
This energy is
produced througt
motion or movement
The havier an object is,
and the faster it moves,
the more kinetic energy it
8. ELECTRICAL
Electrial energy is used
to power machine.
We can transform it into
light, sound, heat and
movement
A lot of our electricity is still
procuced by burning fossil
fuels
Electricity can also be generated
using energy from sunlight, wind,
water and biomass.
9. THERMAL
Thermal energy
flows from a warm
substance to a
cooler substance,
This flow is called
heat
A change in the
thermal energy of a
substance can also
make the
substance cange
state
12. WIND
This energy is clean and
renewable but wind
turbines only work in
windy places
They can also
damage habitasts
and kill birds
13. WATER
This energy is renewable and doesn´t
create pollution, but the construction of
dams damges habitats and causes
biodiversity loss
14. BIOMASS
Organic m material
derived from living
thing wood, dried
vegetation, food
waste
Biomas is burned -> steam
produce turs turbine ->
electricity
Causes air pollution
15. GEOTHERMAL
Heat produce by the
decompesion of
undergraund
radioactive.
Dosen’t pollute
Limited to certain
geographic ares
17. uranium
Nuclear power
stations use a
radioactive metal to
generate electricity
We have enought to
generate electricity for
many centuries
Stations
* Are expensive
* Produce radioactive waste products (can cause
cancer)
