How to make entities fall?

[Artsy]

THANK YOU.
But is there like a way to disable COMPLETE interaction with the entity when it falls?
I mean I can't touch it but I can move it just by walking by it. I set the entity's body mass to 1 btw. Not sure if that's right.

Edit: Never mind, forgot to uncheck Pushed by character gravity.
Edit 2: Had some problems with it as I even got out of the map because the force was so big. Fixed it by setting the entity's body mass to 20. All is good. No problems.
