Unit 6:Light and sound
- Enegy
- It is the ability to do work
- Most of the enrgy
comes from the sun
- Forms energy:Light,Sound and
Electricity
- We transform enrgy from one
to another
- Different types of enrgy
- Solar enrgy
- It comes from the sun
- Solar panels transform solar
enrgy into heat and electricity
- Wind enrgy
- It comes from the wind
- Windmills transform wind
enrgy into electricity
- Hydropower energy
- It comes from the moving water
- We transform the enrgy of moving water into
electricity
- Thermal enrgy
- heat enrgy
- It is inside every substance
- Geothermal energy
- It comes from the Earth`core
- We transform geothermal energy into
electricity
- Biomass
- It is organic material made from living
organisms.Example=rubbish,wood,crops
- We transform biomass into heat
and other products(gases and
fuels
- Mechanical energy
- It`s produced by objects in motion
- Example=Wind enrgy
- Chemical energy
- It comes from chemical reactions
- Petroleum and natural gas produca
chamical energy
- Electrical energy
- It comes from electrons
- Renewable energy sources
- You can use again and again
- They are no going to disappear
- Thet are good for the enviroment
- Sun,Wind,Hyfropower...
- Non-renewlable energy sources
- You can use them once
- They can disappear
- They are bad for the enviroment
- Natural gas,oil,coal...
- Nuclear energy
- Atom=Form every object
- We use nuclear energy to produce electricity
- Coal
- Combustible rock
- Plants
- Cola-mines=We use coal to produce heat
and electricity
- Oil
- Of animal and plants
- Oil=petroleum-petrol
- We use oil to produce electricity and petrol
- Natural gas
- Ch4
- Of animals and plants
- We uise oil to produce electricity and petrol
