- Effort distance (E.D.): the distance moved by the point where the effort is applied.
- Load distance (L.D.): the distance through which the load is raised.
- Velocity ratio: effort distance divided by load distance, a number with no unit.
- Input work: effort multiplied by effort distance, measured in joules.
- Output work: load multiplied by load distance, measured in joules.
- Efficiency: output work divided by input work, written as a percentage, symbol η.
- Friction: the force opposing motion where surfaces rub, which turns part of the input work into heat.
