version of the event.
The trajectory of a fall is important, but there are other
aspects of a fall, such as the launch and landing phases of the
fall, which can also be investigated using physical measurements
and calculations. These include measurements of the
speeds at which a person can run, jump, dive, be pushed or
thrown, an estimate of the rotational speed associated with
each launch method, measurements or estimates of runup
and takeoff distances, calculations of possible trajectories
based on different launch angles and wind speeds, location of
the center of mass of a person on video data, and an analysis
of possible bounce and impact events.
