What is the conceptual interpretation of the integral of displacement?

[Nathew]

I know derivative of displacement gives you velocity, and dv/dt=a.
And I know the integral of a is v and the integral of v is x. So what's the integral of displacement give you conceptually?

Well have a think about it:
The area under the displacement-time graph would have units of meter-seconds.
