Efficiency
-
Inefficient energy transfers are because some energy is converted to heat and either escapes or is released into the surroundings

Theory
Energy
-
Never lost, only changes form. Energy conversion is called an energy transformation
-
Work
Positive, F and s are in the same direction
Negative, F and s are in opposite directions
None, F is perpendicular to s
In order for work to be done, there must be a change in energy
