What is the function of the following parts of a rocket?
A. Fins- Stabilizes rocket during flight. Without fins, the rocket would wobble in flight and would land in an unpredicted spot. B. Recovery Wadding- Prevents parachute from being melted from ejection charge. Still allows parachute to be ejected, allowing safe recovery C. Shock Cord- Connects parachute, nose cone, and fuselage so that parachute safely recovers all parts of an airplane. Otherwise, parts of the rocket would fall to earth in free fall and would be damaged. 2. Consider what happens throughout the flight of a rocket. A. During the launch phase of the flight which is greater, the thrust of the rocket engine or the total weight of the rocket (with motor)? The thrust during the launch phase is greater. In order for lift-off to occur, lift must overcome the force of weight, so the thrust must be greater than the total weight. B. When a rocket runs out of fuel it enters the coast phase and thrust is no longer being produced. What two forces slow the rockets upward flight? Both w
