CATAPULTS OBJECTIVE:

CREATE AND UTILIZE A CATAPULT TO ANALYZE PROJECTILE MOTION.


INSTRUCTIONS: 

  EACH PAIR OF STUDENTS WILL BUILD AND USE A CATAPULT TO PROPEL A LARGE EGG OVER A WALL, ONE METER IN HEIGHT. THE CATAPULT MAY BE NO CLOSER THAN ONE AND A HALF METERS FROM THE WALL.


SPECIFICATIONS:

EACH CATAPULT MAY HAVE A MASS NO GREATER THAN ONE KILOGRAM AND A HEIGHT NO MORE THAN ONE-HALF METER. CATAPULTS ARE RESTRICTED TO THE USE OF A LEVER-ARM DESIGN ACCELERATED FORWARD BY A RESTORING FORCE.
RANKING:    TO RANK STUDENTS MUST PROPEL THE EGG OVER THE WALL SAFELY. CATAPULTS WILL BE RANKED USING A RATIO OF DISTANCE IN CENTIMETERS TO WEIGHT OF DEVICE IN KILOGRAMS.
