What constitutes a "low-power rocket"?

A low-power rocket is defined primarily by the specifications of its motor, specifically its total impulse. The total impulse of a rocket motor is a measure of how much thrust the motor can produce over time, and for a rocket to classify as low-power, it must have a motor with a total impulse of less than 80 Newton-seconds. This definition ensures that low-power rockets operate within certain safety limits and are suitable for youth and hobbyists, allowing for less stringent regulatory oversight and making them accessible for educational purposes and recreational use.

Other options do not accurately capture the required standards for classifying a low-power rocket. For example, while the height a rocket can achieve or its weight could provide some context, they do not specifically define the low-power category. Indoor launch capability is also not relevant to the classification of a rocket as low-power because it pertains more to the environment in which a rocket is flown rather than the characteristics of the rocket itself. Thus, recognizing the total impulse as the key factor is essential for understanding the classification of low-power rockets.
