Plot F vs. t while pulling block with
force sensor to show that
the force of static friction can
take on a
range of values,
the maximum force of static friction
is greater
than the force of kinetic friction,
the force of kinetic friction is
proportional
to the normal force,
the force of kinetic friction is
independent
of area,
with display of v vs. t, the
frictional force
is independent of velocity. (This is less reliable, in part because it
is difficult to maintain a constant force while pulling at higher
speeds.)
NOTES
Zero the force sensor in horizontal
position
before collecting data.
Make sure force sensor # agrees with
that
of calibration file.
