what units do we use to measure energy
Joules/Kilojoules
Newtons
KG
cm³
what is the law of conservation of energy
Energy can be created or destroyed, and it can be transferred
Energy can not be created or destroyed, it can only be the same.
Energy cannot be created or destroyed, it can only be transferred
Energy can be created but not destroyed, and it cannot be transferred
Name the 10 energy types
thermal, kinetic, drag, light, sound, chemical, electrical, nuclear, elastic, gravitational potential
thermal, kinetic, light, sound, chemical, electrical, nuclear, elastic, gravitational potential
thermal, kinetic, light, sound, chemical, water, nuclear, elastic, gravitational potential
where do we get out energy from
Our sleep (elastic energy)
food (chemical energy)
unhealthy food (fat)
what does renewable mean
an energy resource that can be replaced in one's lifetime and will not run out.
an energy resource that can be replaced in one lifetime but will run out
an energy resource that can not be replaced in one lifetime but will not run out
name some examples of renewable resources
solar, wind, geothermal, hydroelectric, wave, biomass
thermal, kinetic, light, sound, chemical, electrical, nuclear, elastic, gravitational
protein, carbs, lipids, vitamins, minerals, fat, omega
give advantages of renewable energy
they cannot be destroyed, but can be transferred
they will never run out
the cause pollution
wave, solar, biomass
they create little or no pollution
give disadvantages of renewable energy
they will run out
they don't provide as much energy as non renewable resources
they are unreliable and depend on the weather
energy cannot be created or destroyed, only transferred.
they ruin people's views and they are unattractive
what does non renewable mean
they will never run out and can be replaced in one's lifetime
they will run out but they will be replaced with new plants
they will run out and they cannot be replaced in one's lifetime
energy that is: coal, oil, gas
name examples of non renewable energy
wave, solar, wind, geothermal
fossil fuels like coal, oil, gas and nuclear.
dams that are built do spin generators
give advantages of non renewable energy
produce a lot of energy
they are not situated near urban sites
they rely on weather
they don't rely on weather
they will never run out
give disadvantages of non renewable resources
limited supply
burning fossil fuels releases co2 into atmosphere
they make the view look ugly
contributes to global warming and climate change
they make the surrounding area cold and bare
what are fuels
something we use for energy
something we burn for thermal energy
something that propels our cars forward with thrust
something that involves friction
what are fossil fuels
old fuel that nobody uses anymore
something that is a limited supply and should be conserved
fuel formed from dead matter over millions of years
coal, oil, natural gas
how is electricity generated in power station
water is heated to produce steam which is used to turn a turbine which turns a generator. inside generator a magnet turns in a coil of wire, which generates electrical current
water is heated to produce steam which is used to turn a turbine which turns a motor. inside motor a magnet turns in a coil of wire, which generates electrical current

what diagram is this
sankey diagram
distance-time graph
bar chart
line graph
when we change energy from one form to another, some energy is useful. what about the rest
it is used for other appliances
it's wasted
it changes the atmosphere of the room
what type of energy does an object have because of its position or height
kinetic
sound
gravitational potential
nuclear
in a power station what turns the turbines
thermal energy
cogs
a jet of steam
people working there
in a torch what type of energy is wasted
light
sound
electric
thermal
what type of energy does a TV transform electrical energy into
light
kinetic
heat
sound
gravitational potential
what is the transfer of energy on a pendulum
gravitational potential when it is high up to kinetic to when it is coming down etc. etc.
thermal to sound when it hits other pendulums
gravitational potential when it is low down and when it is coming down kinetic
what type of energy does a washing machine transform electrical energy into
kinetic
elastic
sound
chemical
heat
