In classical mechanics, a constraint on a system is a parameter that the system must obey. For example, a box sliding down a slope must remain on the slope. There are two different types of constraints: holonomic and non-holonomic.[1]

In this system the box slides down a slope, the constraint is that the box must remain on the slope (it cannot go through it or start flying).
