whatts=?
joules per second
name 3 renewable energy recourses
solar, wind, tidal ,geothermic ect
what is power measured in
whatts
what is time measured in
seconds
what is the equation for calculating energy
energy=power× time
what does the energy in the kinetic enrgy store depend on
the objects mass and speed
what is power
the rate at which energy is transferred
name three non renweable energy resources
coal, gas, oil
energy is not used up but it is…
transferred beteween energy stores
what are renweable energy reasources
they are energy reasorces that will never run out [the energy can be renewed]
energy/time=?
power
time=?
energy/power
are energy reasources renweable or non renewbale
they can be either
can energy be created
no
what does GPE stand for
gravitational potential energy
can energy be destroyed
no
what is energy measured in
joules
name 3 uses of energy resourses
transportation, heating, electricty
name 2 fossil fules
coal ,oil ,gas
what are other uses of energy resources
transport and heating
