Friction in unity?

Is there any friction in unity? If so, how can I change the friction on an object to almost stick to every object it touches? If not, how can I simulate friction?

Give your object a rigidbody component and adjust the angular drag.

Hi, yes there is friction.

Right Click → Create → Physics Material / Physics Material 2D

There is the Static / Dynamic Friction and the Bounciness values that you can change. Then simply add the physic material to the objects you want to affect with friction.
