Can you help me to understand the difference beetwen these words? I understood the meaning is "why" and they are used always for the questions, but i didn't understand the difference.

Answer

Зачем? -  for what purpose? 
Почему? -  for what reason? 
There is almost no difference, in some questions they are synonymous. 
You can use both variants, It will not be wrong.

Answer

зачем
- literally 'for what’
- more concerned with goals or actions in the future
- reply usually begins with 'чтобы’ or 'затем, что’
почему
- literally 'by what means’
- more concerned with reasons, causes or consequences in the past
- reply usually begins with 'потому что’
For example:
Зачем ты открыл окно? To let in some fresh air.
Почему ты открыл окно? Because I’m cold.
'Зачем’ is also less formal, apparently.

Answer

why - почему
for what - зачем/для чего

Answer

Почему? - the reason of some action.
Зачем? -  the aim of some action.
Sometimes they can be synonymous, like: 
Зачем/почему ты изучаешь русский язык? 
When they are NOT synonymous:
Сегодня я не буду работать. You can ask Почему? but cannot use Зачем?

Answer

Зачем? - perchè? (Se si intende il scopo)
Почему? - perchè? (Se si intende il motivo)
