The mass of an object is the same wherever it may be. The weight of an object changes however. The weight of an object is the product of its mass times gravity. Gravity is greater on earth than it is on the moon, so an object will weigh more on earth.
The escape velocity is higher for Earth than for the Moon. Earth's escape velocity is approximately 11.2 km/s, while the Moon's escape velocity is about 2.4 km/s. This is because Earth is more massive and has a stronger gravitational pull compared to the Moon.

What will happen if a satellite has velocity which is more than orbital vellocity but less than escape velocity?
If a satellite has velocity greater than the orbital velocity but less than the escape velocity, it will move into a higher orbit. However, it will remain in orbit around the central body and will not completely escape its gravitational pull. The satellite will continue to follow a curved path around the central body.
What does the term 'escape velocity' mean?
Escape velocity is the minimum velocity needed for an object to break free from the gravitational pull of a celestial body, such as a planet or moon. It allows an object to overcome gravity and travel into space without being pulled back. The specific escape velocity depends on the mass and radius of the celestial body.
What is takeoff velocity of rocket?
The takeoff velocity of a rocket depends on various factors such as rocket design, size, weight, and fuel capacity. Generally, rockets have a takeoff velocity of around 7-8 km/s to escape Earth's gravity and enter orbit.
How can rockets escape from gravity?
Rockets can escape Earth's gravity by achieving enough velocity to overcome the force of gravity. This is done by propelling the rocket with enough thrust to reach a speed called the escape velocity, which varies depending on the mass of the planet and the height of the rocket above its surface. Once the rocket reaches escape velocity, it can break free from the gravitational pull and travel into space.
How do sideways velocities on the moon compare to sideways velocities on earth?
Sideways velocities on the Moon are lower than on Earth due to its weaker gravitational pull. Objects on the Moon require less velocity to achieve orbit and escape its gravitational influence compared to Earth. This difference is a result of the Moon's smaller size and mass.
Can an intercontinental ballistic missile reach escape velocity?
Yes. Probes have already be sent to the Moon, and other planets; this requires a velocity very near the escape velocity from Earth. Other probes are leaving the Solar System, so they achieved the much higher escape velocity required to escape the attraction from the Sun.
There is no atmosphere on the moon. Explain on the basis of escape velocity?
The moon's escape velocity is lower than the average velocity of gas particles in its atmosphere, so the moon cannot retain an atmosphere as the gas particles would escape into space. This is why the moon has no significant atmosphere.
What is the escape velocity from the moon for a lunar landing module sitting on the Moon's surface?
The escape velocity from the Moon is about 2.38 km/s. To leave the Moon's surface, a lunar landing module would need to reach this speed to overcome the Moon's gravitational pull.
Have any MANNED vehicles reached 'escape velocity' - If so what were they?
Yes, several manned vehicles have reached escape velocity, which is about 25,000 miles per hour. The Apollo spacecraft used during the moon missions reached escape velocity en route to the moon. Also, the Space Shuttle reached escape velocity when it orbited the Earth or traveled to the International Space Station.
The ratio of the radius of that of the moon is 10 .The ratio of g on the earth and on the moon is 6 then what is the ratio of the escape velocity from earth's surface to that from the moon's surface?
The escape velocity is given by √(2gR). Since Rmoon = 0.1REarth, and gMoon = 0.16gEarth, the ratio of escape velocities can be found as: √(2gEarthREarth) / √(2gMoonRMoon) = √((2gEarthREarth) / (2gMoonRMoon)) = √((gEarthREarth) / (gMoonRMoon)) = √((gEarth / gMoon) * (REarth / RMoon)) = √((6 * 1) / (0.16 * 0.1)) = √(6.25) = 2.5. So, the ratio of escape velocity from Earth's surface to that from the Moon's surface is 2.5.
What is te Formula of escape velocity?
Escape velocity is given by. √2gR or √2GM/R .therefore escape velocity is directly prop. to gravity of a planet or star or any other body. More is the gravity more is the escape velocity. The escape velocity of our earth is 11.2 km/s and that of moon is 2.31 km/s
Would a spacecraft need as much fuel to escape from the moons gravity as it would to escape from the earths?
Escape velocity for the moon is a little over 5000 miles per hour. For the earth it is about 25,000 miles per hour. So the moon requires a fifth of the energy required to escape the earth.
What will happen if a satellite has velocity which is more than orbital vellocity but less than escape velocity?
If a satellite has velocity greater than the orbital velocity but less than the escape velocity, it will move into a higher orbit. However, it will remain in orbit around the central body and will not completely escape its gravitational pull. The satellite will continue to follow a curved path around the central body.

What is them minimum initial speed for escape?
If you mean to escape into space, that is called the "escape velocity". How much this is depends on whether you are talking about planet Earth, the Moon, the Sun, Jupiter, Sirius B, etc.
Can you help with this question The space rocket only needed to go 1.4 kilometres per second to escape the Moon's gravitational pull on the way back Why is this less than taking off from Earth?
The rocket leaving Earth has to overcome the Earth's gravitational pull, which is much larger than the Moon's. The "escape velocity" for Earth is nearly 5 times that of the Moon's escape velocity, which is actually about 2.4 kilometers per second. Actually, the details of how spaceflight works are more complicated than that, but the basic idea is correct.
What is the escape velocity of the moon Charon?
The escape velocity of Charon, the largest moon of Pluto, is about 550 meters per second. This is the minimum velocity an object must have to overcome Charon's gravitational pull and escape into space.
