Rockets need to be ignited to initiate the combustion of propellant, which produces the high-pressure and high-temperature gases necessary for thrust. This combustion process generates the force that propels the rocket upward by expelling gases at high speed in the opposite direction, according to Newton's third law of motion. Ignition ensures that the propellant burns efficiently and consistently, allowing the rocket to achieve the necessary velocity to escape Earth's gravity.

Where do some rockets get their oxygen from?
Some rockets, such as liquid fuel rockets, carry liquid oxygen (LOX) as an oxidizer in a separate tank. The LOX is then mixed with the rocket's fuel and ignited to create thrust. Other rockets, like solid fuel rockets, have an oxidizer mixed into their solid fuel composition.
Why do bottle rockets need water to fly?
Bottle rockets require water to create steam pressure within the bottle. This pressure builds up when the water inside is heated by the ignited propellant, causing the bottle to launch upwards. The steam escaping through the nozzle propels the bottle rocket into the air.
What is the difference between solid rockets and liquid rockets?
Solid rockets use solid propellant that is already mixed together and cannot be turned off once ignited, providing simplicity and reliability but less flexibility in performance control. Liquid rockets use a liquid propellant that can be precisely controlled and shut off, offering better performance and efficiency but requiring more complex systems for fuel storage, management, and engine design.
What needs To burn fuel in rocket?
You need a fuel. You need something that will react or "burn" with it. This is called an oxidizer, even though oxygen is not always what is used. You need a means of forcing the fuel into a combustion chamber. You need a combustion chamber. And you need an exhaust bell for the spent fuel to leave! Some rockets need an igniter, something to set the fuel and oxidizer off. Other rockets use "hypergolic" fuels, which means that the fuel and oxidizer go off just by coming into contact. This is good because not having an igniter means one less thing that can go wrong. The lunar module had this kind of engine. Solid rockets have the fuel and oxidizer mixed together, just waiting to be ignited. The burning fuel hollows the rocket out, forming a sort of combustion chamber.
Why do rockets need wings?
because without the wings the plane would be unstable and crash. by:jake tompson

Do rockets need energy?
Yes, rockets need energy for launching

What are solid rockets?
The correct term is "solid propellant rocket". These are rockets that burn fuel that is not a liquid(or they are NOT liquid fuel rockets). These rockets have a fuel that is poured into the rocket case and turns to a solid. Once ignited, there is no stopping the burn or controlling it.A simple example of this is rocket you shoot on the 4th of July. It burns black powder that has been formed into a cardboard case.Whereas, a liquid fuel rocket can be controlled by varying the amount of fuel that is injected into the rocket motor.

How are rockets useful?
Because if we didn't have rockets there would be no such thing as rockets and we need them because the word "Rockets" sounds like pockets and we like words that rhyme don't we.
Why have rockets?
You need rockets so you can travel to space and visit other planets. Without rockets we would know nothing about astronomy.

What types of products does Estes Rockets provide?
Estes rockets is a great company for kids! Their main product are model rockets and associated rocket engines that can be launched for fun. Their rockets used to be sold as kits but they now offer a fully assembled line. Their engines are labled with a letter, then a number, dash, and number, e.g. C6-7. The first letter is power, the number is length of burn time and the last is the delay until the parachute charge is ignited.

Can rockets be launched in vacuum?
Yes. Rockets have both a fuel and an oxidizing agent, so they don't need air.
When was the first Chinese Rocket invented?
Around 499 AD. The Chinese ignited saltpeter, sulfur and charcoal in hollow bamboo tubes to shoot projectiles - including rats. These rockets were actually called 'flaming rat rockets'.
