That's what this is called; this is a dashpot.
-
A dashpot is an idealized physical model of a viscous liquid.
-
One way to imagine it is that it's a cylinder,
-
the black cylinder here,
-
inside of a hollow cylinder.
-
So, it's a cylinder inside of a hollow cylinder and
-
there's some friction between the outside wall of the black cylinder
-
and the inside wall of the hollow cylinder.
-
There's some well-behaved, well-known friction
-
between the inside of the hollow cylinder
-
and the outside of the inner cylinder.

Now--then if I apply a force,
