energy Flashcards
what are energy forms
give me examples
are the different ways in which energy can appear
such as heat, light, sound, nuclear kinetic, gravitational potential and chemical energy
what are energy resources
are the different ways of supplying a particular energy
such as coal,oil and wind
whats the definition for chemical energy
whats examples of its resources
the energy stored within a substance which is released on burning
eg coal oil natural gas turf wood and food
whats the definition for gravitational energy
whats examples of its resources
the energy a body contains in result of being above the ground (height above ground)
stored energy in the dam of a hydroelectric power station
whats the definition for kinetic energy
whats examples of its resources
the energy moving a object (due to speed)
wind waves tides
whats the definition for nuclear energy and what are examples of its resources
the energy stored in the nucleus of a atom
uranium, plutonium
the fundamental law of physics is the principle of conservation of energy what does it mean
energy can neither be created nor destroyed but it can change its form
other common energy sources are electrical, magnetic and strain potential, describe the energys body
when it has been stretched or squeezed out of shape and will return to its normal shape when the force is removed
such as a wind-up toy
what is renewable energy
is energy that is being replaced by nature in less than a human lifetime it will never run out
whats non-renewable energy
is energy that will eventually run out
give me a example of non renewable reasources
fossil fuels
nuclear power
give me examples of renewable resources
geothermal power stations
tidal barrages
biomass
wave machines
solar cells
etc
whats the main input and output energy of a mircophone
sound
electricity
whats the main input and output energy of a room heater
electricity
heat
whats the main input and output energy of a burning match
chemical
heat
what do all energy resources rely on
the sun
what do fossil resources come from
and how is it linked to the sun
dead remains of plants
the plants have to get energy from photosynthesis
what energy does not rely on the sun
geothermal and nuclear energy
