'Anwenden' (to apply/use) is a separable verb. The prefix 'an-' goes at the end in a main clause. In subordinate clauses and in the infinitive with 'zu', the verb stays together.
Der Arzt wendet eine neue Behandlungsmethode an.
The doctor applies a new treatment method.
The verb consists of the prefix 'an' and the verb 'wenden' (to turn, direct). Figuratively, 'anwenden' (to apply/use) therefore means to 'turn' a method or knowledge 'toward' a specific situation or direct it at that situation.
Man muss die Theorie auf die Praxis anwenden können.
You have to be able to apply theory to practice.
This meaning is often used with abstract concepts. Typical objects are: 'eine Regel anwenden' (to apply a rule), 'ein Gesetz anwenden' (to apply a law), 'Wissen anwenden' (to apply knowledge), 'eine Technik anwenden' (to use a technique), or 'eine Methode anwenden' (to apply/use a method).

In this meaning, 'anwenden' (to use/apply) is almost always combined with words that describe a form of coercion or force. Common combinations are: 'Gewalt anwenden' (to use force/violence), 'Druck anwenden' (to apply pressure), or 'Zwang anwenden' (to use coercion).
Der Täter hat körperliche Gewalt angewendet.
The perpetrator used physical force.
This meaning is always used reflexively and with the preposition 'an' + accusative. The structure is: 'sich an jemanden/etwas anwenden' (to turn to someone/something).

'nutzen' and 'anwenden' can both mean that you use something in a practical way. The difference lies in the object: 'nutzen' fits many things, for example a tool, time, an opportunity, or an offer. 'anwenden' is used especially with rules, knowledge, methods, or something learned. Learners may confuse the words because both sound like 'verwenden' (to use). A practical tip: you use an app or an opportunity; you apply a rule, technique, or method.
