An Elevator Ride

Accelerating objects - elevator

 

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.

Materials:

Elevator Car, CBL, accelerometer and a TI-83. Alternative procedure with stored data: just TI-83 or a PC with Excel .
