They should be about 1/10 of total length.
Fins.
If it didn't have wings, it'd be a rocket.
This depends on many things, it varies with the agle you are goint to shoot it with and the funktion of the rocket (length, stability, perhaps returning to the shooter) Assuming your rocket is to be launched straight up in the air the wings is only a mean of stabilizing it. For this kind of rocket the wings should be hard and has as little resistance as possible The shape should be like the triangular ones you see in the movies and you should use about 3 or 4 of them hope this helps:)
Not really the shape, but things like large fins or wings can be knocked off in hard landings.
by its wings
it affects because. well actually it depends on the rocket just research it
the bird have wings while the rocket have none
they stabelise the rocket in motion and steer it like a steering wheel
Some rockets do have wings. Then again if the rocket operates in space, wings won't do any good. Most big rockets have control systems that swivel their main engines to balance the rocket.
A rocket is a form of propulsion. If a rocket is used to power an airplane, it is referred to as a rocket-plane, and has wings like an airplane. It the rocket is use to propel a vehicle vertically, which does not need wicgs to provide lift, it is called simply a rocket. Sometimes fins are used to stabilize or guide a rocket in flight, but these are referred to as fins rather than wings.
Fins are small aerodynamic wings attached to the rear of the rocket. These are to give guidance and stop it from spinning.
The pronoun that takes the place of the plural noun wings is they as the subject of a sentence or clause and them as the object of a verb or a preposition.The penguin has short wings. They are not used for flying. The penguin uses them to aid in swimming.
