Which is a liquid fuel used in rocket engines?
AMMONIA
What speed rocket starts?
A rocket's speed at launch is typically zero, as it starts from a stationary position on the ground. The rocket gradually accelerates as it is propelled by its engines, reaching higher speeds as it ascends into space.
How does the law of force and acceleration apply to lanch of a rocket?
The law of force and acceleration, described by Newton's second law (F = ma), applies to a rocket launch by illustrating how the force generated by rocket engines propels the vehicle upward. As the engines burn fuel, they produce a thrust force that must overcome the gravitational pull acting on the rocket. The resulting acceleration of the rocket is directly proportional to the net force (thrust minus weight) and inversely proportional to its mass. As fuel is consumed, the mass decreases, allowing for greater acceleration as the rocket ascends.
How is the Saturn V rocket put together?
—the Saturn v had two stages both parts would burn its engines until the fuel ran out then it would come off the rocket
Is thrust on the rocket in the absence of gravitational force of attraction constant?
Yes, the thrust on the rocket remains constant in the absence of gravitational force. Thrust is the force pushing the rocket forward, generated by the propulsion system. It is independent of gravitational force.
What are two main types of rocket engines?
The two main types of rocket engines are Solid fuel rocket engines and Liquid fuel rocket engines.
Why only rocket engines can be propelled to space?
Rocket engines are not air breathing engines and hence they can be propelled into space.
What is rocket cryogenic engines?
Rocket engine
How many rocket engines did the Saturn V have?
The Saturn V rocket had five rocket engines in its first stage, called the F-1 engines. These engines were responsible for providing the necessary thrust to lift the rocket off the ground and into space.
What are model rocket engines and what do they do?
Model rocket engines are reproductions of rocket engines that are scaled down to a much smaller size than the real thing. They usually don't do anything and are for display purposes.
Action-reaction engines that propel an object forward?
a rocket
What is a example of a rocket fires engines and lifts off?
the rocket is accelerating
How many engines does a rocket have?
4
What type of engine powers a rocket?
Rockets are powered by rocket engines, which operate on the principle of propulsion through the expulsion of high-speed exhaust gases. There are two main types of rocket engines: liquid rocket engines, which burn liquid propellants, and solid rocket engines, which use solid propellants. These engines generate thrust based on Newton's third law of motion, where the expulsion of gas in one direction propels the rocket in the opposite direction. Additionally, some rockets may employ hybrid engines that combine both liquid and solid propellants.
How rocket ship take off?
A rocket ship takes off by igniting its rocket engines, which produce thrust that propels the ship upward. The force generated by the rocket engines pushes the ship off the ground and into the air, overcoming Earth's gravity. As the rocket ascends, its engines continue to provide thrust to propel it further into space.
