what is the equation for work done?
force x distance moved
1 of 12
what is work done measured in?
joules
2 of 12
what do work done and energy transferred have in common?
they are equal
3 of 12
describe the energy transfer of wind to electricity
kinetic energy from the wind turns a turbine which turns a generator which produces electricity
4 of 12
describe the energy transfer of water to electricity
kinetic energy from water turns a turbine which turns a generator which produces electricity
5 of 12
describe the energy transfer of geothermal resources to electricity
thermal energy heats water, water turns into steam, the thermal energy of the steam then turns a turbine which then has kinetic energy, the turbine turns a generator which produces electricity
6 of 12
describe the energy transfer of solar heating systems to electricity
thermal energy from the sun heats water which turns into steam that turns a turbine that then has kinetic energy, the turbine turn a generator which produces electricity
7 of 12
describe the energy transfer of solar cells to electricity
light energy from the sun is transferred into electrical energy
8 of 12
describe the energy transfer of fossil fuels to electricity
chemical energy is burnt to form heat energy as it causes water to evaporate, the kinetic energy of the steam is used to make a turbine spin which is connected to a generator transferring it to electricity
9 of 12
describe the energy transfer of nuclear power to electricity
chemical energy is burnt to heat water which turns to kinetic energy that turns a turbine connected to a generator which produces elecricity
10 of 12
how is energy transferred by conduction?
when heat is applied to a solid the particles begin to vibrate. These particles vibrate faster and faster throughout the entire material heating it up
11 of 12
how is energy transferred by convection?
In liquids and gases when heat is applied the particles gain energy(thermal-kinetic)and move faster. They move further apart and become less dense causing heat particles to rise. Eventually they cool again and sink; creating a convection current
