| Orbit | the path that an astronomical object such as a planet moon or ssatellite follows around a larger astronomical object such as the Sun |
| Component | a part of something usually of something bigger |
| streamlined | to design or build something with a smooth shape so that it moves with minimum resistance through air |
| Payload | the passengers equipment or satellites carried by a spacecraft or the weight of these |
| Apogee | the point farthest from the Earth an object rocket reaches while it moves around the Earth |
| Motor Time Delay | the length of time between the motor's thrust phase and the time that a small explosion occurs for the recovery phase |
| Misfire | to fail to ignite the fuel mixture in the engine or to ignite it at the wrong time |
| Center of Gravity | the point through which the sum of gravitational forces on a body can be considered to act ( the teeter totter point) |
| Wadding | soft material used to protect the recovery system |
| Baseline | Distance from the launch pad |
| slant angle | the angle up to the top of the rocket at its highest point |
| average speed | average speed=distance/time |
| Height | Height= TAN ( clant angle) X baseline |
| Propulsion | the force by which an object such as an automobile ship aircraft or missle is moved forward. |
