Verbs can be used in the active, passive and reflexive forms.
When the subject of the sentence is performing the action we use the active form:
Luca lancia la palla.
Luca throws the ball.
When the subject of the sentence has something done to it and does not do it itself, we use the passive form:
La palla è lanciata da Luca.
The ball is thrown by Luca.
When the subject does the action to itself, we use the reflexive form:
Io mi lavo la faccia.
I wash my face.
