Chemical rockets combine a fuel chemical and an oxidizer chemical to produce combustion products (a new, combined chemical with an ever-so-slightly lower mass than the components, and lots of energy). In the space shuttle main engine (SSME) the fuel was liquid hydrogen (other common liquid fuels are alcohol and kerosene) and the oxidizer was liquid oxygen. The rocket engine is a bell with an open end, or nozzle. When the hydrogen and oxygen are combined in the bell, they burn to produce water vapor and energy. The released energy forces the mass of the water vapor out the open end of the engine in one direction and, by conservation of momentum (Newton's third law), the mass of the rocket is propelled in the opposite direction.
So, rather than a specific additive, everything that is burned in the engine provides mass that contributes to the momentum that propels the rocket.
What else can I help you with?
A rocket engine obtains forward momentum through the use of fuel additives?
fandango additives usually which contain oxygen
Rocket engines can obtain momentum with fuel additives called what?
Rocket engines can obtain momentum with fuel additives known as "oxidizers." These substances enhance the combustion of fuel, allowing for more efficient propulsion. Common oxidizers include liquid oxygen and ammonium perchlorate, which help to increase the energy output of the rocket engine.
How does a rocket travel?
A rocket moves through space by pushing exhaust gases out of its engine in the opposite direction with great force, according to Newton's Third Law of Motion. This generates thrust that propels the rocket forward. By continuously firing its engines and adjusting its trajectory, a rocket can navigate through space to reach its destination.
What are the fuel additives in rocket engines?
Fuel additives in rocket engines are substances added to propellants to enhance performance, stability, and efficiency. Common additives include stabilizers to prevent decomposition, oxidizers to support combustion, and agents that reduce freezing points or improve combustion characteristics. Some formulations also incorporate additives to minimize corrosiveness or reduce the formation of harmful byproducts. These additives help optimize engine performance and ensure safe and reliable operation during launch and flight.
How can a rocket in space shut off its engines and still keep moving?
A rocket in space can shut off its engines and still keep moving due to the principle of inertia. Once the engines are turned off, the rocket will continue to move forward at a constant velocity unless acted upon by another force, such as gravity or a change in trajectory.
What rocket engines can obtain forward momentum with fuel additives?
Rocket engines that can obtain forward momentum with fuel additives include hybrid rocket engines, which use a combination of solid and liquid or gaseous oxidizers. These engines can enhance performance and efficiency by introducing additives like nitric oxide or hydroxyl-terminated polybutadiene (HTPB) into the fuel mix. Additionally, some liquid rocket engines utilize additives in their propellants to improve combustion characteristics and thrust. Overall, the use of fuel additives can optimize engine performance and enable more efficient propulsion.
What causes rocket engines can obtain forward momentum with fuel additives?
Rocket engines achieve forward momentum by expelling exhaust gases at high speeds, based on Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. Fuel additives can enhance combustion efficiency, increase energy output, and improve the overall performance of the propellant, allowing for greater thrust. By optimizing the combustion process, these additives help generate more forceful exhaust, leading to increased acceleration and improved rocket performance.

Rocket works on the principle of conservation of?
linear momentum. A rocket works by expelling gases from one end at a very high velocity. The escaping gases have a very high speed and this with their mass translates to a very large momentum. Due to the principle of conservation of momentum the body of the rocket is pushed forward. If both the momentum of the gases as well as that of the rocket are added the sum is zero.

How does launching your rocket relate to this law of motion?
If a rocket is at rest (zero momentum) in outer space, where there is no gravity, then as long as there are no Outside forces on it its momentum must always be zero (consevation of momentum). This must be true even if an internal explosion brakes it into pieces. The pieces must fly off in such a way that their net vector momentum is zero. Turning on the engine is like an internal explosion. The hot gasses, which have mass, are ejected out the back at high velocity so the gas has momentum. In order to keep the total momentum zero the rocket must move forward so its momentum just equals the backward momentum of the gasses and the net momentum of both is zero. The same is almost true when taking off from earth. Because of the Earth's gravity(outside force) the upward momentum of the rocket won't quite equal the downward momentum of the gasses but its almost the same.
How do the principles of a water bottle rocket relate to real rockets?
Thy operate on the same principle. The water going backwards has momentum that is balanced by the rocket going forward.
What makes a rocket move forward?
A rocket moves forward by expelling high-speed exhaust gases out of its engines, following Newton's third law of motion which states that for every action there is an equal and opposite reaction. As the gases are forced out of the rocket at a high velocity, the rocket experiences a thrust in the opposite direction, propelling it forward.
