PHY.6:4.3 - Supply the response and configuration relations

For each unresolved interaction that affects the answer, state how its response depends on the physical conditions. Use an applicable theory, an established material response, an available measurement or a stated working hypothesis. PHY.4 helps constrain a law whose form is unknown; MMP.11 helps represent its remaining freedom.

Recover the conditions under which the relation is used. Does it describe the current state, dependence on earlier states, a spatial gradient, an average response or fluctuations? Does it assume a settled contact, a constant material parameter or a particular preparation? Supply the configuration relations needed to connect that response to the retained variables.

Keep physical restrictions that the chosen description relies on. A passive damping law transfers mechanical energy into other forms; it does not destroy total energy. If that heating changes the response during the intended use, include the resulting dependence. A fitted or learned response can also supply a relation, but its physical restrictions and usable range must come from its construction or grounds, not from the fact that it produces numbers.

When several physically plausible laws remain, derive what each changes in the requested consequence. A bound or a conditional answer may be sufficient. Seek another observation or a more detailed account when its possible result can change the work; C.11.DUA helps decide that inquiry.
