RE: Force Sensors Must Measure Acceleration?? (fwd)

I am noticing that now we are talking about instruments, not human senses.
Yesterday I was asking myself three questions. 1) do I have a sens of
acceleration (or force)? 2) where is it located 3) do my sound sensing
mechanisms responds to pressure or to intensity? I was tempted to answer
the second question in public but did not know how to say it politely. It
is close to the sensor which reacts when I feel "vertigo (?)"

Which particular instrument are we to vote about? Ludwik

That's really why I thought we better have two separate threads -- the
earlier one on sensing or feeling acceleration (human senses), and the
present one dealing with the proposition that someone had never
encountered a force detector that didn't measure acceleration first.
To register your conclusions on human sensing abilities the other thread
would probably be more appropriate. This subject line (Force Must
Measure Acceleration??) is more to see if linguistic usage, such as "g's,"
"g-forces," Etc., has so changed the thinking and language of current
physicists that it is really impossible, or at least not useful, to
distinguish forces from accelerations, or dynamics from kinematics.
But granted, the two themes are closely related.
