Applied force keeps the node moving

I am creating a top-down game of pool. The entire view is the table, and then I have number of ball-nodes. When I apply force to the balls, they keep moving for quite long time, where I'd like the force to wear off faster. Since I haven't been working too much with physics before I am having a difficult time figuring out which propert(y/ies) to adjust.

I have a quite high restitution (0.8) on the balls, because I want them to bounce off the edges. The edges are defined by this node:

SKPhysicsBody(edgeLoopFrom: CGRect(x: -self.size.width/2.0, y: -self.size.height/2.0, width: self.size.width, height: self.size.height))

I see that there is a friction property on the SKShapeNode class. I am feeling that it might be the right one to use, but it doesn't seem to help when I turn it up.

So what is the right approach - how do I make the applied force wear off faster?

Adjusting the physics body's linearDamping property will allow you to change the rate at which the body slows over time (linearDamping doc). The value should be between 0 and 1.0, where 0 results in no damping and 1 provides maximum damping (slows faster).
