If a plane is in level flight, gravity (weight) is equal to lift.
That deppends... if you mean the atmosphere which would equal zero gravity than yes but the earths gravitational pull is what keeps the moon where it is so the planes or helicopters wouldn't be able to get completely out of the pull

Thrust. The pull of the propellers, the push of the jet engine, the pull of gravity.
Pluto's force of gravity is equal to 0.58m/s2, whereas the force of gravity on Earth is 9.81m/s2. Thus, the gravity on Pluto is about 6% that of the gravity on Earth.
Gravity only appears to pull upwards relative to your position. Einsteins theory of relativity comes into play here, and as you can only be in one place at any given time you are only affected by the pull of the objects gravity you are on. Besides if the two objects had the same gravity they would remain where they were.
A plane flies using equal and opposite actions by overcoming gravity with lift and drag with thrust.
because the friction involved in the box sliding down has overcome the pull of gravity.
The object floats in the water.
the pull of gravity on a camera is its weight
Yes - in fact, anything that has mass will exert a gravitational force (including comparably small objects, like a human being). Pluto's force of gravity is equal to 0.58m/s2, which is about 6% that of the gravity on Earth.
Gravity is always equal to nine.eight meters per second, except when gravity is at another pull... ex) another planet or a gravity chamber in a science lab
Gravity on a plane is less then on a hill because you are away from the earth, However gravity in a plane over a hill is more then gravity on a plane over a valley at the same altitude above sea level.
