Abstract

Parametric inertia and API techniques are described. In one or more implementations, functionality is exposed via an application programming interface by an operating system of a computing device to one or more applications that is configured to calculate an effect of inertia for movement in a user interface. The calculated effect of inertia for the movement on the user interface is managed by the operating system based on one or more rest points specified using one or more parametric curves by the one or more applications via interaction with the application programming interface.
