Any force larger than the weight is sufficient, if it is applied long enough.

How much thrust is needed to escape earths gravity if something weighs 1520 pounds?
The general idea is that the escape velocity from Earth is 11.2 km/second. This assumes there is no atmosphere. I guess "thrust" would be expressed in units of force; the force can be just about anything, from just slightly bit more than the object's weight (to counter Earth's gravity), to a lot more, depending how long the force is applied. In other words, if you apply more force, you need to apply the force for less time to achieve escape velocity.
What to you use to measure the amount of force needed to pull something?
You can use the force gravity to measure the amount of force, because gravity makes an object tied to a string hang.
Is a magnetic field needed to create gravity?
No.
Is gravity needed for buoyancy?
Gravity is needed for buoyancy as if there was no gravity then there would be no need for buoyancy, the need for buoyancy is to counteract the pull of gravity so you can stay at the surface of a liquid such as water. If there was no gravity then there would be no need to counteract it. I hope this the answer you needed. What if there is a ball of water in space and a cork made dof wood is inserted carefully into the ball. Would it 'rise' from the center of the ball towards the surface or not???
Is force needed to pick up an object?
When you pick things up, you apply lift. This is as opposed to something like levers, which still lifts something, but usually involves you applying downward force.

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 speed maintained by a rocket if it is launced in outer space so it will escape the earth's gravity?
According to most sources, the minimum speed needed to escape the Earth's gravity is 11.2km/s, so a rocket would need to travel at least this fast to get into outer space.
What kind of force is needed to launch rocket ships?
to break off from earths gravity they need to reach speed of 11.2 kilometers per second
Which requires more fuel -- a rocket going from the Earth to the Moon or a rocket coming from the Moon to Earth?
the moon because it has only one sixth of the gravitational pull that Earth does

How fast does Saturn v go?
over 24,000 miles per hour, on the final burn, which is 7 miles per second, which speed is needed to escape earths gravitational pull.
Why are map projecters needed?
to draw the earths surface.
What is a consideration in planning an escape?
To determine what escape aids and tools are needed.
What effect did the Great Depression have on sports?
they were better because ppl needed to be able to escape to something they enjoyed so sports began tp prosper
When you go on different planets it takes more energy to move something than it is on Earth Is it more gravity or less gravity?
Other planets have more or less gravity than Earth, so the energy needed to move things around is also more or less.
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")
