Principle:
It is is easier to calculate speed when one
assumes
that air resistance does not impact flight
speed.
Hypothesis:A
rocket with an aerodynamic nose will fly faster
and higher than a rocket with a blunt
nose.
Experiment:
Take the pneumatic
rocket launcher and
inclinometer
outside. Wear safety
glasses, keep safety on until
field of fire is clear of personnel and rocket is
aimed in a safe
direction. Set Launcher at 85 degrees.
- Have observer take
Inclinometer 100 feet away from
launch.
- Pump pressure to 60 psi;
Insert and fire rocket with blunt
nose and measure how high the rocket
flies.
- Pump pressure to 60 psi;
Insert and fire rocket with
pointed nose and measure how high the rocket
flies.
Conclusions:
Have students do calculations and discuss
what
they learned.
