ENERGY - Coggle Diagram
ENERGY
forms
kinetic energy
thermal energy
molecular random motion
temperature (K) = T(C)+273
gravitational potential energy
energy to lift object against gravity
potentail energy = force x distance = weight x height = m x g xH
electrical
nuclear energy
fission
splitting the atom (uranium)
fusion
putting together 2 atoms (hydrogen)
energy bound up in the nucleus
criteria of sustainable energy
not substantially deleted by continuous use
no significant pollution or other environmental problems
perpetuation of hazardous health hazards or social injustice
power is rate energy converted from one form to another
unit W (watt)
joule per second
measured as kWh(kilowatt hour)
power (W) = voltage(V) x current (I)
capacity to do work
force (N)= ma
energy(J) = force(N) x distance (m)
efficiency
percentage efficiency = (energy output/energy input) x 100
capacity factor
capacity factor = (actual output over a given time)/ (theoretical output for given time)
energy is conserved - first law of thermodynamics
