How do rockets escape from earths gravitational pull?
when the rockets push they create a certain amount of thrust which is need to get the rocket off the ground. As the rocket gets higher the air friction becomes less so the rocket travels faster , most of the force is needed to get away from Earth. To completely escape the earth's gravitational pull the crew must reach a distance of at least 400 km away, that is why the iss (international space station) is at an average distance of 250 km from the earth constantly. The pull is strong enough to keep them at a distance, but not strong enough to pull them back to the ground.
The speed and direction a rocket must travel to break away from a planet's gravitational pull is called?
To escape the gravitation pull of an object you must travel at or in excess of the escape velocity. The direction of the escape velocity is always radially outward from the center of the object.
What speed do rockets break earths gravitational pull?
Enough to support their own weight, plus a little more for motion. It is possible, in theory, to imagine a rocket moving away from the Earth at a slow walking pace. In real life you don't do that, you get away from Earth's pull as quickly as you can manage to do so.
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.
Why you must study escape velocity?
You don't. "Escape velocity" is a meaningless number. "Escape velocity" is the speed at which a CANNON SHELL must be fired in order to escape from the Earth's gravity well. With a powered rocket, you can "escape" from the Earth's gravity at ANY speed - as long as you have enough fuel.
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.
What will a rocket do if it reaches escape velocity?
If a rocket reaches escape velocity, it will be able to break free from a celestial body's gravitational pull and travel into space indefinitely without falling back to the surface. This velocity ensures that the rocket's kinetic energy is greater than the potential energy at that altitude, allowing it to overcome gravity's influence.
How rocket leaves the earthin easy sentences?
My rocket leaves the Earth in ten minutes. The rocket will roar into space shortly thereafter. Utilizing the latest magnetic levitation technology, the rocket will escape Earth's gravitational pull within minutes of it's launch.
Does a rocket always need the escape of 11.2 to escape the earth?
That's the initial speed the rocket would need to escape Earth, assuming it starts close to Earth, and no additional impulse is provided later. With a gradual impulse - for example an ion impulse - i.e., providing impulse over time, it isn't necessary to start with this speed. However, the rocket still needs the same total amount of energy to escape from Earth.
Which requires less fuel launching a rocket from the earth or space?
Earth has gravity so less fuel is needed to move a rocket in space(assume that you mean escape from earth's gravitational field by"from earth")
The speed and direction a rocket must travel to break away from a planet's gravitational pull is called?
To escape the gravitation pull of an object you must travel at or in excess of the escape velocity. The direction of the escape velocity is always radially outward from the center of the object.
Can you escape a black hole?
By building a machine that travels through space (like a rocket), and fly it against the direction of the Black Hole. For as long as the thrust of your rocket is above the gravitational pull of the Black Hole, you are away.
What may happen to a rocket which rises from the earth never attains escape velocity?
A rocket that doesn't reach "escape velocity" will be overcome by gravity and will be pulled back down to Earth. Also, rockets which go into orbit have not reached escape velocity. Escape velocity is what is needed to completely leave earth's gravity well.
What is the sentence of acelerate?
The rocket will have to accelerate in order to escape the bonds of Earth's gravitational pull.Accelerate now!
Which requires more fuel -- a rocket going from the Earth to the Moon or a rocket coming from the Moon to Earth?
A rocket traveling from the Earth to the Moon requires more fuel due to Earth's stronger gravitational pull. The rocket needs to overcome Earth's gravity to escape its orbit, which requires a significant amount of energy compared to landing and taking off from the Moon, where the gravitational pull is weaker.
