Escape velocity is defined to be the minimum velocity an object must have in order to escape the gravitational field of the earth, that is, escape the earth without ever falling back.
From the surface of the Earth, escape velocity (ignoring air friction) is about 7 miles per second, (11.2 km/sec) or about 25,000 miles per hour. Given that initial speed, an object needs no additional force applied to completely escape Earth's gravity.

Achieve escape velocity: By accelerating an object to a speed greater than the escape velocity of a planet or celestial body, it can escape the gravitational pull. Utilize propulsion systems: Using rockets or other propulsion methods to counteract the force of gravity and lift off from Earth or another planetary body.
Escape velocity from Earth depends only on the mass of the Earth and the distance from its center, not the mass or size of the rocket. All rockets need to reach the same escape velocity to leave Earth's gravitational pull, regardless of their size.
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.
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.
A black hole is an object with such strong gravity that not even light can escape its pull. This intense gravity is due to its extreme density, formed when a massive star collapses in on itself.
To reach outer space, rockets must escape the force of gravity. Gravity is the force that pulls objects towards the center of a mass, such as the Earth. Rockets need to generate enough thrust to overcome Earth's gravity and reach escape velocity to enter outer space.
So that it can escape Earth's Gravity. The rockets work by burning so much fuel that they can overpower Earth's gravity.
Today's rockets use chemical fuel for this. That is, they burn something.
Rockets escape Earth's gravitational pull by achieving enough velocity to overcome gravity. They generate thrust by burning fuel, propelling them upward until they reach a speed of around 11 km/s (25,000 mph) - the minimum speed needed to break free from Earth's gravity and reach space.

Rockets are used to propel spacecraft and satellites into space by providing the thrust needed to escape Earth's gravity. They are also used for military applications, such as launching missiles and rockets used for defense purposes. Additionally, rockets are being explored as a potential mode of transportation for future space tourism and exploration missions.
Rockets use thrust to overcome the force of Earth's gravity.
they have to pass some forces in the earths atmosphere They have to overcome the force of gravity, lifting the rocket and all of the fuel to an escape orbit.
gravity pulls down a rocket
Gravity
If a rocket rises from Earth but never attains escape velocity, it will eventually fall back to Earth due to gravity. The rocket's upward thrust will not be enough to overcome Earth's gravitational pull, causing it to return to the planet's surface.
To overcome gravity, you must reach "Escape Velocity" to overcome gravity and escape a planet's orbit.
