What is the acceleration of a space rocket?

The space shuttle gains more altitude above Earth and the speed increases to the nearly 7,850 m/s (17,500 mph) required to achieve orbit. The main engines are commanded by the onboard computer to reduce power, ensuring that acceleration of the space shuttle does not exceed 29.4 m/s2 (3 g).

Why does a rocket’s acceleration increase as it rises?

As altitude increases, the atmosphere, which causes drag, decreases. The same force with less drag acting against it causes a greater acceleration. The rocket is continually using the fuel, causing the total mass of the rocket to go down. The same force with less mass means you get more acceleration.

Why does a rocket with more mass need more thrust to launch it?

A rocket with more mass will speed up more slowly, just as in the horizontal example, but there is another effect. The force of gravity is now acting in the opposite direction to the thrust, so the resultant force pushing the rocket upwards is also less.

How does the acceleration of the rocket during Stage 1 compare to the acceleration during Stage 2?

moving (both upward and downward) after stage 2 has ended. 6. How does the acceleration of the rocket during stage 1 compare to the acceleration during stage 2? The acceleration are the same.

What was the acceleration of the Saturn 5 rocket?

The Saturn V reached 400 feet per second (120 m/s) at over 1 mile (1,600 m) in altitude.

How are rockets propelled?

In space, rockets zoom around with no air to push against. Rockets and engines in space behave according to Isaac Newton’s third law of motion: Every action produces an equal and opposite reaction. When a rocket shoots fuel out one end, this propels the rocket forward — no air is required.

Do rockets have constant acceleration?

Thus, even though the force on the rocket is constant, the resulting acceleration is not; it is continuously increasing. So, the total change of the rocket’s velocity will depend on the amount of mass of fuel that is burned, and that dependence is not linear.

What is the principle of rocket propulsion determine the acceleration and thrust acting on the rocket?

The propulsion of all rockets is explained by the same physical principle: Newton’s third law of motion. A rocket’s acceleration depends on three major factors: the exhaust velocity, the rate the exhaust is ejected, and the mass of the rocket.

What was the acceleration of Apollo 11?

What is the most powerful rocket engine ever built?

F-1
With 1.5 million pounds (6.7 MN) of thrust, the F-1, built way back in the 50s, remains the most powerful single-chamber rocket engine ever created. With five F-1 engines, Saturn V, which first launched in 1967, is still the largest and most powerful rocket ever created.

How does the model rocket acceleration compare to the Space Shuttle?

The acceleration of the model rocket at 90 m/s2 is far greater than the Space Shuttle at 5.25 m/s2, but there is a significant difference in the motion after launch. Firstly, the model rocket only had enough propellant for 1 second of thrust.

How many times more powerful is a rocket than an engine?

In fact, some rockets can produce 3,000 times more power than an automobile engine of the same size. It is because of this that NASA uses rockets to send satellites and manned missions into space.

What happens at the moment of launch of a rocket?

A model rocket at the moment of launch. The propellant can be seen being ejected from the base. This rocket reaches an altitude of around 100 m. The two forces acting on rockets at the moment of launch are the thrust upwards and the weight downwards.

What makes a chemical rocket different from conventional rockets?

Conventional chemical rockets burn a fuel with an oxidizer to make a gas propellant. Large amounts of the gas push out at relatively low speeds to propel the spacecraft. Image left: Xenon ion discharge from the NSTAR ion thruster of Deep Space 1. Credit: NASA
