The main factor in determining the amount of thrust a rocket requires to leave the Earth's atmosphere is the mass of the rocket. The heavier the rocket, the more thrust is needed to overcome Earth's gravity and propel it into space.
When a rocket leaves Earth, it continues to accelerate to overcome Earth's gravity and reach orbital velocity. Once in space, the rocket enters orbit or continues on its trajectory to its destination. Without the force of Earth's gravity pulling on it, the rocket stays in motion according to the laws of physics.
Payload weight
astronauts leave earth by the liftoff of the space shuttle and rockets, it is called force of the rocket. The engine starts and liquid fuel comes out of the rocket and pushes them up.
He got in the rocket that he and the others used to get there and flew back to earth
69 meters per second
Gravity acts on rockets by letting it leave the ground.
Payload weight.
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.
No, a rocket leaving the moon's surface would not require as great a speed or force as one leaving the Earth's surface. This is because the moon has lower gravity than Earth, so the escape velocity required to overcome gravity and leave the moon is lower than that required to leave Earth.
Payload weight.
Not exactly sure about the actual speed, but it sounds like <8Km/second would not be fast enough to be considered "escape velocity." The speed needed to leave Earth's gravitational field.
