Which type of rocket uses a motor with total impulse of less than 80 Newton-seconds?

The classification of rockets based on total impulse is important in rocket design and regulatory compliance. A rocket that uses a motor with a total impulse of less than 80 Newton-seconds is categorized as a low-power rocket. This classification is significant for hobbyists and those new to rocketry, as low-power rockets typically involve simpler designs and safety guidelines.

Low-power rockets often utilize commercially available motors tailored for first-time builders and enthusiasts. These motors provide enough thrust and impulse to reach modest altitudes, making them an ideal choice for educational purposes and practical experience in rocket construction and launching without the complexities associated with higher impulse categories.

In contrast, mid-power, high-power, and ultra-high-power rockets utilize motors with greater impulse ratings, leading to more complex requirements for building, certification, and launch activities. This classification serves to ensure that hobbyists operate safely and within the appropriate regulatory frameworks established by organizations such as the CAR.
