degree of freedom

 

In regards to mechanical systems, the degree of freedom, or DOF, is the number of independent variables that describe the state of a system.

A coin, for example, has one degree of freedom: the face that is showing (either heads or tails). A rigid body in space has six degrees of freedom, three of which represent it’s location and three that correspond to it’s rotation.
