Forces can cause a spring to compress (not just under gravity), beams to
bend, gases to compress, piezoelectric crystals to produce a voltage
differential, bones to break, and people to say "ouch". Any of these
phenomena (except perhaps the last) can be used to measure a force. I think
that 'force' is a concept that means a lot more than just "ma", and also
happens to be directly experienced by many sentient animals. (02)
