What is friction? (explain if full sentences)

Answer: what comes to mind when we hear the word "Friction"?

Basically friction is a "Force" that opposes an intend (ing) motion.

Explanation:

By motion I mean movement.

By force I mean a body that carries with it energy.

So to understand this better, just see it as a force (thing) that prevents or stops you from taking action.

The resistance that one surface or object encounters when moving over another. The action of one surface or object rubbing against another.
