Energy
- Principle of energy conservation
- "Energy cannot be created or
destroyed but can be transferred
from one place to another or
changed from one form to another"
- "Energy cannot be created or
destroyed but can be transferred
from one place to another or
changed from one form to another"
- intro
- measured in joules/kilojoules
- 1KJ= 1000J
- energy allows work to be done
- energy is always conserved
- measured in joules/kilojoules
- Transducers
- energy changers
- change one type of energy
into another
- *converts energy* total energy going in equals total
energy going out
- energy changers
- Efficiency
- energy used compared to energy wasted
- Useful energy output/ total energy input *100
- higher efficiency = less wastage
- energy efficient lightbulb
- energy efficient lightbulb
- Sankey diagram (energy transfer diagram)
- input
- useful output
- useful output
- input
- energy used compared to energy wasted
- Types of energy
- heat/thermal energy
- type of energy that will
flow from warm area to
colder area
- temperature is how hot
or cold an object is
- type of energy that will
flow from warm area to
colder area
- kinetic energy
- type of energy
that makes
objects move
- type of energy
that makes
objects move
- light energy
- sound energy
- chemical energy
- energy store
- energy store
- electrical energy
- gravitational potential
- potential energy
associated with
gravitational
force
- potential energy
associated with
gravitational
force
- elastic potential
- energy stored
in stretched
objects
- energy stored
in stretched
objects
- nuclear energy
- splitting of
uranium atoms
- splitting of
uranium atoms
- heat/thermal energy
- energy sources
- oil
- burning oil
- burning oil
- gas
- burning gas
- burning gas
- wind
- conversion of wind energy into a useful form of energy
- conversion of wind energy into a useful form of energy
- solar
- uses sun energy to produce electricity
- uses sun energy to produce electricity
- waves
- Waves are generated by the wind as it blows across the sea
surface. Energy is transferred from the wind to the waves.
- Waves are generated by the wind as it blows across the sea
surface. Energy is transferred from the wind to the waves.
- nuclear
- from uranium atoms
- from uranium atoms
- biomass/biofuel
- fuel derived from plant material
- fuel derived from plant material
- geothermal
- thermal energy generated and stored in the Earth
- thermal energy generated and stored in the Earth
- tidal
- form of hydropower that converts the energy
of tides into useful forms of power
- form of hydropower that converts the energy
of tides into useful forms of power
- hydroelectric
- energy is power made by moving water
- energy is power made by moving water
- oil
