Motorcycles
Many of us ride our motorcycles every day using the knowledge we've
gain through learning and experience to keep the bike on the road and
the rider away from the road. Those of us that ride understand
that there are very specific limits to how sharp or fast we can turn
and how these things are related to the size and design of the
bike. Even those that don't ride have intuitive understandings of
the limits of two wheels. The reality is that there is a vast amount of
physics involved in keeping the bike on the road. It is important that
people who ride and even people that don't have a general
understanding
of the physics involved in motorcycles because everyone shares the road
and knowing the limits of other vehicles can help us avoid accidents.
