| Question |
Answer |
| Apogee | the highest altitude a rocket reaches during flight |
| Ballast | 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 | to create or construct according to a plan |
| 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 airflow | smooth, even airflow around the rocket skin |
| Liftoff | occurs when the amount of thrust is greater than 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 straight line with respect to time |
| Wernher von Braun | in charge of developing the V-2 rocket used during World War II |
