Simulate component failures and crashes in Gazebo?

Hi everyone, I am a student who is trying to simulate the behavior of a quadcopter if a certain component fails. I recently began looking into Gazebo and some related videos, but I have yet to see any that simulate a crash, collision, or component failure. For instance, is it possible to stop one motor in midair and observe how the quadcopter crashes? If the drone collides against an object, does it recoil like in real life or just drop vertically?

I am new to the forums, Gazebo, and ArduPilot, so sorry if this post is in the wrong category!
