Something that adds weight in order to improve stability or performance. |
| Center of Gravity |
The point on the rocket where all mass appears to be concentrated. |
| Center of Pressure |
The center of all of the drag forces acting upon the rocket. |
| Constraint |
Limit |
| Design |

| Drag |
Force that acts between the object and the fluid and slows the motion of the object. |
| Dr. Robert Goddard |
Known as the father of modern rocketry. |
| Hypothesis |
Prediction based on prior knowledge or previous experimental data. |
| Laminar Air Flow |
Smooth, even airflow around the rocket skin. |
| Liftoff |
Occurs when the amount of thrust is greater then the weight of the rocket. |
| Propellant |
Contains both fuel and an oxidizer. |
| Rocket |
A self propelled device that carries its own fuel. |
| Thrust |
A force exerted upon or against an object to move it in a specific direction. |
| Total Impulse |
The thrust and duration of the rocket engine burn. |
| Turbulent Airflow |
Uneven airflow around the rocket skin increases the amount of drag. |
| Velocity |
The rate of change of position along a strain line with respect to time. |
