Recommended way for applying forces?

Is there a a good way to apply forces to a system? A use case is when you drag an element on a touch device and release it with a specific velocity. You want the element to being thrown into that direction.

Additionally an element could have another force that is being applied on it, so that it will eventually move to a specific end position.

Compare for example the [photo gallery](http://petehunt.github.io/react-touch/#/viewer) of the react-touch demo of Pete Hunt. When you flick with a higher velocity, multiple photos can be navigated at once.

Is there a recommended way for doing this with react-motion?

Start by reading the react-motion API and comparing the linked react-touch photo-gallery demo, especially its flick and navigation behavior. The issue names no source files or tests; done would require an agreed, documented recommendation for applying release velocity and additional forces.
