A Friction Experiment
During an experiment, a crate is pulled along a rough horizontal
surface by a force F⃗ and the magnitude of the
acceleration along the x direction, ax ,
is measured.(Figure 1) The vector F⃗ has a component along
the x direction of magnitude Fx . The
experiment is repeated several times, with different values of
Fx each time, while maintaining a constant value
for, Fy , the vertical component of F⃗
.
