   I think the same could be argued for the freely moving object in a   
   rotating frame. If you're the rotating observer, then you definitely do   
   not want to put your head in the way of a freely moving massive object,   
   because it will appear to be doing work on your face. One can then argue   
   about what is doing work on what, but the damage to the face will be the   
   same.
