Describe the purpose of a launch rod.

The purpose of a launch rod is to guide the rocket during its initial ascent. When a rocket is launched, especially in model rocketry, the launch rod serves as a physical guide that helps keep the rocket stable and aligned during the critical first moments of flight. This guidance ensures that as the rocket ignites and begins to ascend, it follows a correct trajectory, preventing it from veering off course due to winds or other external factors. The launch rod also helps support the rocket until the thrust is sufficient for it to lift off on its own.

While stability during flight can be an important aspect, it is largely about maintaining proper alignment during that initial ascent. Similarly, while measurement and power are vital for other components of a rocketry system, they are not the primary functions of the launch rod. Instead, focusing on its role in guiding the rocket directly addresses the challenges faced at the launch phase.
