Rotate towards up with forces

I think you answered something similar here:

How to stick an entity to a "floor" surface?

Hi everyone! I’m a bit of a noob here, please bear with me. I currently i have my “player” object moving forward on z axis and im trying to make it “stick” to the surface below in this case a cylinder, but the shape might change to have curves so its not a straight cylinder and i would like to create a gravity force for it to stick to the cylindric surface? Im also using a raycast downwards from my vec3 position, but it doesnt seem to respect the rotation of the entity.

If I had to rephrase my question:

Given a desired target heading (I was thinking up, but actually away from camera may be the way I go) and an entity moving in a given direction, as a result of collisions etc, how do I apply a force to smoothly rotate the object toward the target heading?
