A fly (or any other insect) is trapped in my car as I drive to a new location (let's say 50 miles away) where it then flies out when I open my door. Is the insect going to continue on as normal in this new location? Or has me moving it to a new unfamiliar spot doomed it in some way?

If a single photon bounces between two perfectly reflective mirrors indefinitely, would the mirrors continually accelerate away from each other? If so, where is that kinetic energy coming from?
