Subject: 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.
