Events for the 2009 Western Kentucky
Physics Olympics
Judges determine the overall winner
based on each team's score in the five different events.
Event 1: Save the
Citizen
Every supervillain depends on the existence of hapless citizens
to ensure the attention of his/her arch-nemisis
superhero. The hero must be convinced that there is danger involved, but the
officials at the supervillain union impose large
penalties for causing situations that involve actual death and dismemberment of
innocent bystanders. The
object of this Do-Ahead Project is to design a container in which an innocent
bystander (represented by a Pringle) can arrive intact after being sent through
the U.S. Mail from your local post office to this address:    Western Kentucky University    c/o Rick Patterson    P.O. Box 400325    Unversity of Virginia Astronomy    Charlottesville, VA 22904-4325 1. The Pringle must be unaltered
in any fashion. 2. Pack the Pringle in the
smallest container possible (smallest volume, smallest mass). Within the
package, enclose the Pringle in a sealed ziplock-style
plastic bag from, which the Pringle can be easily removed by
the judges. 3. The size of the package must
be bigger than 5 inches by 3 inches (according to US Post Office regulations)
and smaller than 6 inches by 5 inches by 8 inches (such that it can fit into a
standard rural-style mailbox). Using the U.S.
Postal Service, mail the Pringle to the designated address for arrival on or
before Friday, February 27th, 2009. Late deliveries will not be judged. 4. A judge will unpack and remove
the Pringle from all containers and wrappings. The Pringle must be unblemished,
naturally colored, with no cracks or damage evident. A Pringle
which is damaged in the normal process of removing it from its
containers/wrappings will be judged as having failed to survive. 5. Each team's score is
calculated as the sum of points awarded for the Pringle's survival (0 to 50)
and the product of volume (cm3) and mass (g). In case of tie scores, the amount
of postage will be considered (less is better). The team with the lowest score
wins. 6. All contestants will ensure
that their entry works through the application of physics principles and
generally follows the spirit of the competition. For those times when plans go awry and world domination is not
going to happen, the successful supervillain has an
escape plan. Each
team will construct one or more rockets to carry aloft for at least 15 seconds
one raw grade-A medium chicken egg and return egg safely to the ground without any
cracks or other external damage. Any external damage to the egg will result in
a loss of points. Points
earned for time aloft greater than 15 seconds. 1. Teams
that complete the online Physics Olympics registration will be provided with a
rocket kit (Estes Viking rocket, assembly required), eight igniter packs, and
six rocket engines (three C6-3, and three C6-5 engines). A single rocket launch
kit and additional engines are available free of charge from the Physics
Olympics organizers upon request. 2. Teams
may decorate and modify the provided rocket, or construct an alternative
rocket. 3. The
supplied engines are to be used to characterize the rocket’s performance, with
the expectation that teams will perform sufficient practice flights to be able
to understand how the rocket performs with the various engines provided. The
team must decide which type of engine they will use for the competition and
decide how long their rocket will stay aloft after being launched with that
engine. The manufacturer’s specifications for each type of engine are posted at
the Estes website. 4. During
the registration period on the day of the 2009 Physics Olympics, each team will
submit their rocket, the type of engine they wish to use during the three
competition flights, and their prediction for the time the rocket will remain
aloft using that engine. The judges will provide the requested type of engine
and the eggs to be used during the competition. 5. Teams
will be responsible for the safe launch of their rocket for two flights during
the competition. All launches will be controlled by the range
safety officer. The range safety officer will be
the sole arbiter of safety during the competition. Unsafe conduct is grounds
for immediate elimination from the event. 6. Scores
shall be based on total flight duration of the portion of the rocket containing
the egg, measured from the ignition of the rocket’s engine until the moment of
landing or until the rocket can no longer be seen due to distance or to an
obstacle. The official duration will be the median of the times recorded by
three judges, rounded to the nearest 0.01 second. If one or two stopwatches malfunction,
the remaining time(s) will be used. Scores will be computed by taking the
absolute difference between 15 seconds and the measured flight duration to the
nearest 1/100 second (this difference is always a positive number, or zero). 7. The
winner of the competition will be the team who most closely predicts the total
time aloft for their rocket. Ties will be broken using the time of the flight
that is next closest to the median time aloft. 8. Each
part of the rocket must either contain a recovery device or be designed to
glide, tumble unstably, or otherwise return to earth at a velocity that
presents no hazard. Any entry which has a major part (including but not limited
to an expended engine casing) land without a recovery system, or at a velocity
that is judged by an event official to be hazardous, due to recovery system absence,
insufficiency, or malfunction, will be disqualified. 9. Rockets
must be allowed to land at the end of flight without human intervention
(catching) and will be disqualified if there is such intervention. At the end
of the flight the team members are responsible for removing the egg from the
rocket in the presence of a judge. The egg must be presented to the judges, who
will inspect it for damage. 10. All contestants will ensure
that their entry works through the application of physics principles and generally
follows the spirit of the competition. Event 3: Loot Lift
– Communication/Calculation Challenge
Students will use teamwork, communication and calculation skills to devise a plan, using only the resources made available by the judges, to lift as much of the loot as possible from the “vault” up to your get-away vehicle. Event 4: No Touch Flight – Impromptu Team
Activity
It was destined to happen, the superheroes have arrived and you and your villainous henchmen must, once again, live to fight another day. Work with your teammates to use physical principles such as electrostatic repulsion and Bernoulli’s principle to launch and propel your flying ring across the finish line. Activity is the key word for this competition, with the goal being for each team to achieve the desired result as quickly as possible. The situation is designed to reward teamwork and common sense thinking as well as knowledge of physics. Every team will come away with smiles and good memories regardless of how well they master the particular challenge. Event 5: Order-of-Magnitude
Quiz (also known as Fermi Questions)
Arrive at a
reasonable approximation for the value of a complex situation with very little
to no information available to directly compute the answer. In this quiz, the
contestants will need to quickly make assumptions for values to use in simple
calculations in order to arrive at the "correct" answer, stated as
the power of ten of the number that fits the accepted value.
Teams will
receive 7 questions to complete within 15 minutes. The teams can divide the
work in any way they see fit, but only one answer per question per team will be
accepted. Answers will be judged according to how many orders of magnitude
the team's answer is from the judge's solution. The lowest score wins -- 0
points awarded for the answer accepted by the panel of judges, with 1 point
scored per order of magnitude from the accepted value.
Examples of
Order-of-Magnitude Quiz questions include:
How many
electrons enter the starter motor when a new, full-sized pickup starts?
How many times
would a tire of a Ford Taurus rotate when driven from NYC to LA?
Estimate the
number of gallons of gasoline used annually by all the cars in the USA.
