Mechanics Demonstrations
This demonstration is about reaction
time. Any time human reaction is involved in a measurement,
their reaction time is a source of uncertainty. Useful for
pointing out that "human error" is not a specific enough
description at the university level.
This
demonstration is used in the Uncertainty lab in PHYS
