The pressure needed to lift off a rocket from the ground depends on various factors such as the weight of the rocket, gravitational force, air resistance, and the design of the rocket's propulsion system. Rockets use powerful engines to generate thrust that exceeds the force of gravity, allowing them to lift off. Typically, rocket engines produce millions of pounds of thrust to achieve liftoff.

How does a rocket use lift and thrust?
Rockets use thrust generated by their engines to push them forward and overcome gravity. They do not rely on lift as traditional airplanes do, as they operate in the vacuum of space. The propulsion from the engines creates the necessary force to lift the rocket off the ground and into space.
How much pressure would be needed to lift weight of 10000 N resting on a piston that has an area of 5m2?
The pressure needed can be calculated using the formula: Pressure = Force / Area. Plugging in the values gives Pressure = 10000 N / 5 m^2 = 2000 Pa. Therefore, a pressure of 2000 Pascal would be needed to lift a weight of 10000 N on a piston with an area of 5 m^2.
When a rocket lifts off the ground the net force is in upward direction. Is the upward pushing force greater or lesser than the downward pull of gravity.?
Greater
Which law explains how rockets lift off from the ground?
Newton's third law of motion explains how rockets lift off from the ground. The law states that for every action, there is an equal and opposite reaction. This means that as the rocket propels exhaust gases downward, the rocket is propelled upward in the opposite direction.
How does a rocket achieve lift?
A rocket achieves lift through the reaction force produced by expelling high-speed exhaust gases out of its engines. This action creates thrust, propelling the rocket upwards in accordance with Newton's third law of motion.
What kind of force is needed to launch rocket ships?
Rocket ships are launched by a combination of forces, including the thrust generated by the rocket engines and the force needed to overcome gravity. The thrust from the rocket engines propels the rocket forward, while the force needed to overcome gravity allows the rocket to lift off the ground and enter into space.
How does a rocket get off the ground?
A rocket gets off the ground through a process called ignition. Once the rocket's engines are ignited, they generate thrust, which propels the rocket upwards. The thrust created by the engines overcomes the force of gravity, allowing the rocket to lift off the ground and enter into space.
The first stage of a multi stage rocket is called what?
The first stage of a multi-stage rocket is called the booster stage. It is responsible for providing the initial thrust needed to lift the rocket off the ground and begin the ascent to space. Once its fuel is expended, it separates from the rocket to reduce weight and allow the next stage to continue the journey.
A rocket achieves lift off due to what?
Burning rocket fuel exerts pressure on the rocket nozzle. Note that this happens regardless of whether there is any air for the exhaust to push against. It is simply a matter of expanding gasses which exert pressure.
What 2 forces are present during a lift off of a rocket?

What does the weight of the airplane have to do with the lift of it?
The weight of an aircraft counteracts the lift produced by an aircraft. The heavier an aircraft weighs the greater the lift needed to get off the ground.
What is lift from a rocket?
Rockets do not have lift, they have thrust.
How does a rocket create lift?
thrust. thrust is how a rocket creates lift. thrust is simply the difference in potential energy between the nozzle and the combustion chamber, the difference creates a pressure differential which causes the rocket to move. To go up the rocket must be perfectly balanced and the rocket frame must be strong enough to withstand and balance the thrust.
What three things are needed for flight?
Differences in air pressure, an angle of attack, and lift
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.
How does a rocket take off and what forces are involved?
A rocket takes off by igniting its engines, which produce thrust that propels the rocket upward. The main forces involved in the rocket's takeoff are thrust and gravity. Thrust overcomes gravity, allowing the rocket to lift off the ground and travel into space.
