In a system of differential equations used to describe a time-dependent process, a forcing function is a function that appears in the equations and is only a function of time, and not of any of the other variables. In effect, it is a constant for each value of t.

What is an example of a forcing function?

Examples of a forcing function include a recurring meeting, an appointment with a trainer or coach, or a soft deadline where any progress is presented.

What are the forcing functions?

A forcing function is an aspect of a design that prevents the user from taking an action without consciously considering information relevant to that action. It forces conscious attention upon something ("bringing to conciousness") and thus deliberately disrupts the efficient or automatised performance of a task.
