What keeps a rocket stable?
A rocket's stability during flight is primarily maintained through its aerodynamic design and control systems. The center of mass must be located ahead of the center of pressure, ensuring that any aerodynamic forces act to restore the rocket to its intended flight path. Additionally, active control systems, such as fins or gimbaled engines, can adjust the rocket's orientation in response to changes in airflow or trajectory. These factors work together to ensure that the rocket remains stable and on course throughout its ascent.
How does weight thrust lift and drag affect a rocket launch?
Weight refers to the force of gravity acting on the rocket, thrust is the force propelling the rocket upward, lift is the force generated by the rocket's fins to keep it stable, and drag is the resistance encountered as the rocket moves through the air. Weight must be overcome by thrust for the rocket to launch, while lift helps the rocket maintain stability and drag opposes its forward motion. Balancing these forces is crucial for a successful rocket launch.
When a rocket launches what must the thrust of the engines be greater than?
When a rocket launches, the thrust of its engines must be greater than the gravitational force acting on the rocket, which is the weight of the rocket. This ensures that the rocket can overcome Earth's gravity and lift off the ground. Additionally, the thrust must also be sufficient to counteract any atmospheric drag during ascent.

How many fin's should a rocket have?
It depends on a lot of stuffs like how much do you want your rocket to be stabile. But at least it must be 3. For example for the same stability you may have 3 fins that have large surface area or 4 which is smaller or more. When you increase the number of fins with the same surface area then the drag will increase because of the surface friction so 3 or 4 fins are generally used but there is no certain limit of the number of fins .

Why center of pressure is always below cg?
It's not. By your use of the term "center of pressure" I'll make a guess that you're talking about model rocketry. In that case, the center of pressure can be above or below the center of gravity, but you must make it lower in order to make your rocket stable.When a rocket in flight is tipped - say by a gust of wind or some such - it rotates about its center of gravity. (This actually is true of any object in mid air or space, not supported by an outside force.) When the rocket is moving straight along its central axis the fins are not really doing anything. But when the rocket is tipped and its velocity vector is not along its axis, then the fins generate a lateral force, which acts through the center of pressure. (That's what "center of pressure" means.) Now, if the center of pressure is above the center of gravity then the force that the fins apply will make the rocket tip further, and the rocket is unstable. If the center of pressure is below the center of gravity then the force from the fins straightens the rocket out, and the rocket is stable.This is much easier to explain with pictures. See the related link for a fully illustrated explanation.
Do spacings in between model rocket fins matter?
Yes, they must be equidistant around the main tube, and parallel to it, this is very important for stability.
What factors help make a rocket stable?
Rocket stability is primarily influenced by its center of mass (CM) and center of pressure (CP) locations. For a rocket to be stable, the CM must be located ahead of the CP; this configuration helps ensure that any aerodynamic disturbances create corrective motion rather than exacerbating instability. Additionally, design elements such as fins, which increase aerodynamic drag, and a streamlined shape can enhance stability during flight by minimizing rotational forces. Proper thrust vector control can also help maintain stability by allowing for adjustments in flight path.
How can you make the rocket count down in Pokemon Sapphire?
i think you must catch all the pokemons and then go to the rocket. you can catch jirachi inside the rocket
How do you prevent a unstable salt from oxidising?
You must make it stable if it is unstable it will oxidise by definition. You would have to add another element to make the compound stable but you would then be changing it to a stable salt.
How many fins must be attached to the water bottle to give it longest airborne time?
4 to 3 fins
Does the aerodynamics affect the flight of a rocket?
Of course. Your construction and fin alignment must be as near perfect as you can make it.
Is eel kosher?
No, fish must have both scales and fins.
