To cut a long story short, the force on the trolley
is measured when the trolley is static, not during
the drop of the weight.
I can give a verbose description of said apparatus, but
this would be needing diagrams to improve understanding,
in groups where binaries are not permitted.

It's a straw man attack used to prove the case for
E=0.5mv^2 and gravity at 9.8m/s^2
It proves nothing at all, and never will.
1- there are wheels on the trolley so everything with kinetic
energy is complicated.
2- the drop is far too short to show any difference
between 9.8m/s^2 and gravity in m/s per meter of descent.
3- because there is an attachment (the trolley) the drop is
not in free fall.
The whole of robotics is being held back - don't even know if high end
robotics companies still understand what was made years ago. e.g. the
old guys have retired, and the newbies (freshouts) haven't a clue.
