By using rocket motors to apply an upward force to their ship that is
greater than the downward force of gravity.
Exactly what you do with your leg muscles when you want to propel
your own mass up a flight of stairs against the force of gravity.
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.

Astronauts in space experience microgravity, where they are in a state of continuous free fall around the Earth. This creates the sensation of weightlessness. They do not completely overcome gravity, but rather experience an environment where the effects of gravity are significantly reduced due to the spacecraft's orbital motion.
Leaving Earth can have physical effects on the body due to changes in gravity and radiation exposure. It can also have psychological effects such as feelings of isolation and homesickness. Additionally, leaving Earth can have social effects as individuals adapt to new environments and interactions with others.
The first rocket had to overcome Earth's gravity to reach space. It needed to generate enough thrust to propel itself upward and break free from the pull of gravity, allowing it to reach the necessary speed to enter into Earth's orbit.
To overcome gravity when leaving Earth, a spacecraft must reach a high enough speed to break free from Earth's gravitational pull. This is achieved by launching the spacecraft at a high velocity using powerful rockets. Once the spacecraft reaches escape velocity, it can overcome Earth's gravity and continue its journey into space.
To overcome gravity, you must reach "Escape Velocity" to overcome gravity and escape a planet's orbit.
it needs to overcome the gravity of the earth lol

To overcome gravity and leave Earth, you need to achieve escape velocity. This is the speed at which an object must travel to break free from a planet's gravitational pull without any further propulsion. Once you reach escape velocity, you can travel away from Earth and venture into space.

escape velocity if its leaving earths gravity
Rockets use thrust to overcome the force of 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.
Because we are being carried round with it, and the angular velocity is not sufficient to overcome gravity.
