Objective:
In this experiment the objective is to study the motion of an elevator
car measuring its acceleration. The probe is an accelerometer connected to
a CBL or a LabPro. Collected data will be stored in a graphing calculator
and can be analysed either with the calculator or a computer, using
previously collected data.

Gaspard-Gustave de Coriolis, french
mathematician and physicist, studied mechanics and
engineering mathematics, in particular friction, hydraulics,
machine performance and ergonomics. He introduced the terms
'work' and 'kinetic energy' with their present scientific
meaning. Coriolis proposed a unit of work, namely the 'dynamode'.
The unit represents 1000 kilogram-metres and was proposed by
Coriolis as a measure which could provide a sensible unit with
which to measure the work which a person might do, a horse, or
a steam engine. It is not the ideas of 'work' for which
Coriolis is best remembered, however, rather it is for the
Coriolis force . He showed that the laws of motion could be
used in a rotating frame of reference if an extra force called
the Coriolis acceleration is added to the equations of motion.
