If two rockets weigh 2 pounds and 3 pounds respectively, which outcome is expected?

The outcome indicating that the 2-pound rocket achieves a higher altitude can be understood through the principles of rocketry, particularly when considering thrust-to-weight ratio, drag, and engine performance.

In rocketry, a lighter rocket generally possesses a higher thrust-to-weight ratio, which is critical for achieving altitude. This means that the 2-pound rocket, being lighter, is likely to accelerate more quickly and reach a higher altitude in comparison to the 3-pound rocket. The thrust produced by the rocket's engine must overcome the gravitational force acting on it (its weight) to ascend.

Moreover, the aerodynamic design and stability of the rockets also influence their performance. If both rockets are built similarly but differ only in weight, the lighter rocket would typically experience less inertia, allowing it to respond more rapidly to aerodynamic forces and achieve greater altitudes.

While drag plays a role in all rockets, the lighter rocket being able to accelerate more efficiently tends to offset any potential disadvantage due to drag, often resulting in a higher altitude being reached compared to the heavier rocket.
