1 the act of making and return or doing something in return
2 alternating back-and-forth movement
3 mutual interaction; the activity of interchanging or reciprocating [syn: interchange, give-and-take]
- See Reciprocal for mathematical terminology.
Reciprocation is the action in which a body's displacement returns to its starting location in a given time repeatedly. The velocity over which the displacement occurs with each repetition not necessarily being constant. Such an action is usually used to describe quickly moving implements in mechanical objects usually linearly within a given axis, or even in complex displacement/velocity paths. eg. the piston engine is a reciprocating engine with the piston being the object of reciprocation within the lineal axis of the cylinder.
