I want to know the difference of meaning between 'stop'and 'prevent'.

    Driving into a brick wall will stop your car very quickly whereas applying the brakes properly will prevent you from hitting the wall. – AdrianHHH Jul 6 '16 at 11:40

The definition of stop (Oxford Dictionnary) is

(Of an event, action, or process) come to an end; cease to happen

The definition of prevent (Oxford Dictionnary) is

Keep (something) from happening

So the difference between the two is the moment you act. If the action has already started, you stop it. Otherwise you prevent it.
