Roller furling is a sail management system that allows sailors to roll up or unfurl sails from a drum mounted at the forestay. When the sail is furled, it wraps around the drum, reducing sail area for better control in varying wind conditions. To unfurl the sail, the sailor simply pulls on a line that releases the sail from the drum, allowing it to unfurl and catch the wind. This system enhances ease of handling, especially for short-handed sailing.

In the case of most offshore yachts, yes, they can be "reefed" (furled and tied down) to reduce the amount of surface area exposed to the wind. However this does depend on the type of furling gear used, some (mostly jibs) can only be used fully unfurled (In general a solid forestay is required for a roller-reefing jib.)
'Yearling', 'Curling', 'Hurling' and 'furling' (as in furling or unfurling a flag) come to mind; can't think of any more offhand, but I'll give it thought!
Action and reaction forces work while roller staking by the action force being that you and your roller skates move forward. The reaction force is when the roller skates slide backwards on the ground.

YES, they sure will.
roller ball pens employ a mobile ball and liquid ink to produce a smoother line.
