| 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 |
