Why does a rocket need a large thrust on take off from the earth?
A rocket needs a large thrust on takeoff from Earth to overcome the force of gravity pulling it down. The large thrust is necessary to generate enough speed to reach escape velocity and break free from Earth's gravitational pull. Once the rocket is in space, it needs less thrust to maintain its course.
What is the speed a rocket needs to go past Earth's gravitational force?
Escape velocity from Earth is approximately 11.2 km/s, which is the speed a rocket needs to surpass Earth's gravitational force and leave its orbit.
How does a rocket get out of earths orbit?
A rocket gets out of Earth's orbit by achieving escape velocity, which is the speed needed to break free from the gravitational pull of Earth. The rocket's engines provide thrust to accelerate it to this speed, allowing it to overcome Earth's gravity and travel into deep space.
How fast is a take off of a rocket?
The speed of a rocket during takeoff varies depending on its size and intended destination. Rockets typically accelerate rapidly, reaching speeds of several thousand kilometers per hour within seconds of launch. For example, the Apollo 11 mission to the moon reached speeds of about 39,000 km/h (24,000 mph) at takeoff.
How long does it take a rocket at average speed to escape earths atmosphere?
It takes around 8 minutes for a rocket to reach space and escape Earth's atmosphere. This can vary slightly depending on the specific rocket and its speed.

What is takeoff velocity of rocket?
Exactly the same way it takes off from the earth. Gravity on the moon is so relativistically low that the propulsion required to reach an escape velocity is very very low compared to the earth.
Rocket A travels with speed 0.800c relative to the earth Rocket B passes rocket A with speed 0.500c relative to rocket A Determine the speed of rocket B relative to the earth Assume that the earth?
0.929c formula is: vbe =( vae +vba )/(1+( vae *vba )/c2 )
What you think the rocket kinetic energy is right after takeoff?
The rocket's kinetic energy right after takeoff is at its maximum as it is moving at its highest velocity at that point. The kinetic energy of the rocket is a measure of the energy it possesses due to its motion.
What is the difference of takeoff climb out speed and takeoff safety speed for helicopter?
Takeoff climb out speed is the speed for twin engine climb out and will get performance of best rate of climb and also it is known as (vbroc) but takeoff safety speed is the speed at which the helicopter may safely air born with one engine inoperatied and also it is known as (v2)
What is Rocket speed per sec to escape from earth gravity?
the rocket speed required to escape out of the earth's gravity is known as escape velocity which is numerically equal to 11.2 km per sec.
What is the speed a rocket needs to go past Earth's gravitational force?
Escape velocity from Earth is approximately 11.2 km/s, which is the speed a rocket needs to surpass Earth's gravitational force and leave its orbit.

How long it will take a time if people will go to sun from earth by rocket?
It would take about 19 years to travel by rocket from Earth to the Sun, assuming the rocket is traveling at a speed of 36,000 miles per hour. The distance between the Earth and the Sun is about 93 million miles, so the time to travel will depend on the speed of the rocket.
What is the meaning of 'V2' speed in aviation?
In aviation, 'V2' speed refers to the takeoff safety speed. It is the minimum speed at which an aircraft can safely continue a takeoff in the event of an engine failure. Pilots use V2 speed as a reference point during the takeoff phase to ensure the aircraft has enough performance to safely climb and maneuver.
What is the name for the speed a rocket must reach to escape the earth's gravity?
Escape velocity is the speed that a rocket must reach to break free from Earth's gravity and enter space. It is the minimum velocity required for an object to overcome the pull of Earth's gravity.
Why does a rocket start vertically and then why doesnt it keep going vertically?
A vertical takeoff enables a rocket to get through the atmosphere with the least amount of fuel and drag. After takeoff, the rocket will progressively lean over to a more horizontal position because it follows the gravity turn trajectory.
