
Center of Gravity - the point within something at which gravity can be considered
to act

Nozzle - a projecting spout from which a fluid is discharged

Nose Cone - front consisting of the conical head of a missile or rocket that
protects the payload from heat during its passage through the atmosphere

Fin - a stabilizer that resembles the fins of a fish

Apogee - highest point; the point farthest from the earth; OP. perigee

Altimeter - an instrument that measures the height above ground

Drag - pull, as against a resistance

Thrust - the act of applying force to propel something

Gravity - the force of attraction between all masses in the universe

Inertia - the tendency of a body to maintain is state of rest or uniform motion
unless acted upon by an external force


Velocity - the speed of an object in a particular direction
Aerodynamics - The study of forces and the resulting motion of objects through the air.
Unbalanced Force - two or more forces that are not equal and opposite of one
another; can cause change in motion
Mass - a body of matter without definite shape
Force - move with force, "He pushed the table into a corner"
Acceleration - a rate of change of velocity
Body Tube - Holds the compressed air
Recovery System - purpose is to return the rocket safely to earth; includes parachutes,
streamer, tumble system, helicopter, or glider
Thrust Phase - when the rocket is blasting water out the nozzle
Momentum - the force or speed with which something moves
Payload - the cargo carried by the rocket
Tomy Timer - timer to control the deployment of the parachute
Parachute – material that enhances drag
Page 3: Newton’s 3 laws

Newton's 1st Law
 (Law
of Inertia) an object in motion tends to stay in
motion & an object at rest stays at rest unless acted
upon by an outside force.

Newton’s 2nd Law
 (Force)
when force is applied to an object it is
accelerated in the direction of the force. (mass and
force are inversely proportional)

Newton's 3rd Law
 For
every action there is an equal and opposite
reaction
Page 4: Objective

Build a bottle rocket that spends the longest
time in the air.
 Side

better because …..

Page 6: Bottle Rocket Drawing

On your page (please use full page, large drawing):

Please draw your design.
Page 7: 1 liter Results
Please record the time in the air for all 1 liter bottles. Please write down
their name and the time their rocket spent in the air.
Page 8: 2 liter Results

Please record the time in the air for all 2 liter bottles. Please write
down their name and the time their rocket spent in the air.
Page 9: 1 vs 2 liter bottles

Please use the data you collected and analyze which did better, 1
liter or 2 liter rockets. Please tell me
Page 10: Bottle Rocket Result

Please write a summary of how your bottle rocket preformed. Please
include 6 of your vocabulary words in your summary. Please
underline or box your vocab words so I can tell you used them.
