CP3e Non Renewable Resources Flashcards
Gravitational Potential Energy (calculation)
change in gravitational potential energy (J) = mass (kg) x gravitational field strength (10 N/kg) x change in vertical height (m)
GPE = m x g x h
Kinetic Energy (Calculation)
Kinetic Energy (J) = 1/2 x mass (kg) x velocity2 (m/s)2 KE = 1/2 x m x v2
Everytime something is moved upwards…
The more gravitational potential energy is stored
Non-renewable
An energy source that will run out because you cannot renew your supply of it
Most electricity used in the UK is generated using nuclear fuels or fossile fuels such as…
Coal, oil and natural gas
Describe two reasons why fuels made from oil are used in vehicles
Petrol and diesel are fossile fuels made from oil. They are used in most vehicles because they store alot of energy and they are easy to store and to use in engines
Burning fossil fuels release
Carbon dioxide and other gases
Carbon dioxide emission contribute to…
Climate change
Burning natural gas causes less pollution than…
Burning coal
Natural gas power stations also emit less c________ d_______ than other fossile fuelled power stations producing the s________ amount of e_________.
carbon dioxide
same
electricity
Nuclear power stations do not emit any carbon dioxide or other gases, however the waste they produce is
Radioactive
Disposing of radioactive waste safely is
Expensive
It costs a lot more to build a nuclear power station and to dismantle it safely than…
Building a fossil fuelled power station
Renewable
An energy resource that will never run out
Examples of renewable energy resources
Solar power and wind energy
