Example of high friction is a really rough surface like sandpaper.

high friction materials can prevent sliding under high loads or steeps incline.insome situations,adding a libricant actually increases the friction, due to molecular effect.
Rubber will have a high coefficient of friction on most surfaces, but we cannot know whether there is more or less friction unless we have something to compare it to.

A force is a push or pull on an object some ex are friction
