Energy
|
def: capacity/ strength to produce work
*cannot be destroyed, can only be converted |
|
|
Forms of energy
|
chemical
potential kinetic electrical thermal radiant nuclear sound magnetic ionization elastic gravitational |
|
|
Energy Transfer
|
def: amount of energy that changes form can be measured by work done
work done= force x displacement W= Fs W= Joules F= Force s= displacement |
|
|
Power
|
def: work done in a certain amount of time
power= work done/ time = energy transfer/ time P= w/t = J/s unit= J/s |
|
|
Efficiency
|
Efficiency= output power/ input power x 100%
