What key feature distinguishes high-power rocketry from low-power rocketry?

The key feature that distinguishes high-power rocketry from low-power rocketry is the power and size of the rocket motors used. High-power rockets employ large motors that can produce significantly greater thrust and are designed to burn for longer periods. This increased power allows high-power rockets to reach higher altitudes and achieve more complex flight profiles compared to low-power rockets, which utilize smaller, commercially available motors.

The distinction is fundamental, as it directly influences not only the performance and capabilities of the rockets but also the regulations governing their launches. High-power rocketry typically requires special certifications, launch sites, and safety measures due to the greater risks associated with powerful motors, making the type of motors a critical differentiator in the rocketry community.
