Our experiment is to determine the relationship
between the diameter of a parachute and the
average speed of its decent with a constant
weight.
We did this by dropping 4 different size
parachutes for 47 meters then to see which
parachute dropped the fastest.

Theoretical Background
We had many hypotheses that we wanted to prove or
disprove today. Three of them were 1 Using
each weights speed, we should be able to create
an average ratio of area to average
velocity. 2 Using that ratio, we should be able
to figure out the average speed of a parachute
with a different size. 3 Our data should show a
straight diagonal line in a graph that shows
1/Area Vs. Velocity2.

Results
Our experiment showed that the parachutes
followed the graph for faster moving objects,
which is 1/A Vs. velocity2, instead of just 1/A
Vs. Velocity Using our data we can predict that
a parachute with a radius of 35 would have an
average falling velocity of 2.2 m/s.
