During this project we constructed and launched a bottle rocket in order to investigate projectile motion. Projectile motion is the motion of an object thrown or projected into the air, subject to only the acceleration of gravity. The object is called a projectile, and its path is called its trajectory. 

Wings and Fins

We added three wings on each side of our bottle rocket. Each was spaced 120 designs apart to make the rocket aerodynamic. Small fins were then added to the wings to direct the rocket's movement upward.

Nose Cone

We added a nose cone to make the cone more aerodynamic. This cone would decrease air resistance and make the rocket fly high.

Weight 

My group made the rocket as small and light as possible to ensure it wouldn't be weighed down.

Final Position = (initial velocity) x (time) – (0.5)(32)(time)^2

Final Position = 0 (the rocket is back on the ground)

Time = the total time the rocket was in the air 

Our time = 3 seconds

Initial velocity = 49.28 ft/sec
