I conducted an experiment using an accelerometer w/ a
90sec interval on a rollercoaster. the accelerometer was started b4 the
1st initial drop. I'm not sure the # are accurate. is it possible to send
me numbers from a previous experiment. if not thanks for trying. i
I do not know if you are using a mechanical accelerometer (spring or
protractor) or an electronic one (such as TI/Vernier). Without that
information, it will be difficult to give you an exact answer. I find that
the electronic ones are very difficult to analyze since roller coasters
accelerate in three dimensions. It is usually very difficult to correlate
the postions on the track where a paarticular acceleration occurred.
Without knowing the specific roller coaster, it is hard to tell what the
maximum accelerations might be.
In general, rollercoasters have an acceleration in the range of 20 m/s^2 to
38 m/s^2 at the bottom of the first drop. This depends on radius of the
curve at the bottom, height of drop, and position in the train.
I hope this helps!
