Re: [Phys-L] feeler-dealer, third law, et cetera



True or false: If an object is subject to a force F, some
other object must be subject to a force -F, simultaneously.

Assume short distances and long times, so we don't need to
fuss over the meaning simultaneity in special relativity.

True of false: The pairing of F with -F is absolutely required
by third law of motion.

Please do NOT spend more than a few minutes thinking about
this. I will post my answers soon.
