Static model is a time independent view of a system . however static modelling is supposed to detail what preferrably might happen instead of the numerous possibilities. that's why it is more rigid and cannot be changed. therefore, it is called static modelling . use case can be a part of both static and dynamic modelling depending on how it is designed. normally it is, a part of static modelling . it includes
class diagram
object diagram
component diagram
deployment diagram

.Dynamic Modeling
it is time dependent and more appropriately it shows what an object does essentially with many possibilities that may arise. it is flexible but its flexibility is limited to the design on the system.
it includes
use case
interaction
state chart
activity
