I am currently thinking about frame dragging and what effects it would have on a body falling towards a dense object under the influence of gravity. I have looked at the Kerr metric but haven't yet worked out what all the functions actually represent.

For an overview, look at our old friend Wikipedia.

Apparently, frame dragging imparting angular momentum to an orbiting body is a larger effect than frame dragging on a body falling straight towards a dense object. I guess partly because frame dragging has more time to act on an orbiting body than a falling body?

At the moment I am looking at the Schwarzschild metric and a straight line path to towards the centre of gravity. I want to start by excluding frame dragging and avoid parabolic functions. The profile of this path can then be a baseline. This will show up extremes where an orbital won't.
