What about using the term impulse to describe a large but exceptionally
force? Is this a well defined concept?
Justin Parke
Sure it is. Unfortunately automobiles are often stopped by large brief
forces administered by things like large trees. Dashboards used to be bare
metal. They typically exerted forces over a shorter time period and
therefore require a larger force to change the momentum of the occupant.
Since we now cover dashes with foam rubber the time that dashboards are in
contact applying forces to the occupant has increased this allows a smaller
force to change the momentum of the occupant.
