if i put an ad in my free app does that make it commercial instead of educational?

If i put an ad in my free app, is it now considered a commercial app instead of an educational one? basically my app uses copyrighted material, which is allowed under the 'fair use' section of copyright law, if i provide the app for free, i know it is legit for sure... but if i put the add in it is it now a commercial use instead of an educational one?

tons of websites use copyrighted material under 'fair use' and also have ads on the website... why would this be any different? or would it?

So would the ad change the use of my free app to commercial use and the use of that material to copyright infringement or am i ok?

It's definitely commercial.

Whether it's fair use or not is impossible to say without knowing more about how you use the material. Or better yet, without your lawyer knowing more about how you use the material.
