It isn't clear what exactly you mean with "escape gravity". The effects of Earth's gravity (for example) extend all the way to infinity, while getting weaker and weaker at a greater distance. So in a way, an object moving away from Earth never "escapes gravity". If an object moves fast enough - about 11.2 km/second near Earth's surface - it is said to have reached "escape velocity", in this case, it is fast enough never to come back. A rocket will reach escape velocity in a few minutes.

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.
How long does it take a rocket to get to the moon?
takes about 2-4 days, depending on gravity
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 forces are used in take off in a rocket?
Thrust is the main force used in take off in a rocket. It is the force generated by the rocket engines which propels the rocket upwards. Gravity and aerodynamic forces also play a role in the take off phase.
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.
Why does a rocket take more fuel to launch off the moon than earth?
Actually its the other way around, if a rocket were to launch off the moon it would take less fuel than if it had launched off of earth. It would take less fuel because the moon has lighter gravity.
How is gravity and thrust both involved when launching a rocket?
Gravity plays the major role in the launch.. a rocket has to cross the escape velocity so as to get out of the atmosphere. Escape Velocity is the speed at which any space shuttel or rocket or anything has to achieve if it wants to escape the earth's gravitational field. Gravity attracts the rocket and all the things coming from the space and going in to the space from the earth towards itself.. that is the reason that whenever you jump, you come back to earth!!!
Why is it easier for a rocket to take off from the moon?
Gravity is weaker because the moon has less mass.
How long does it take to escape earth atmosphere in a rocket ship?
It takes approximately 8-10 minutes for a rocket to reach space and escape Earth's atmosphere. This timeline can vary depending on factors like the size of the rocket, its speed, and the specific trajectory it follows.
How long does it take for a rocket to get built?
depends on the rocket... you're clever.
How long does it take a rocket to escape the earth's atmosphere?
It usually takes a rocket about 10-15 minutes to reach the edge of the Earth's atmosphere and officially enter outer space. Once in space, the rocket continues to accelerate to reach the necessary escape velocity of about 25,000 miles per hour to break free from Earth's gravitational pull.
Does it matter which way a rocket is pointed for it to escape from earth?
No but if it is pointed straight up, it will take less fuel.
