Efficiency
________: how much useful work is done with energy supplied.
Power
________: is the rate at which a machine transfers energy.
→Because work
________ done is equal to energy transferred, the power is also equal to the rate of doing work.
Energy
amount of work and its measured in Joules (J)
Conservation of energy
energy cannot be created or destroyed, when work is done, energy is changed from one form to another
Efficiency
how much useful work is done with energy supplied
Renewable sources
Energy sources that are not exhaustible/ Infinite
Non-renewable sources
Energy sources that are exhaustible/ finite
Work
Work is done whenever a force acts on an object that moves (or is moving) in the direction of the force
Power
