Any upward force on an object can be less than, equal to, or greater than the force
of gravity on that object. It all depends on the object's mass and distance from the
center of the Earth.
Lift is the upward force that opposes the force of gravity.
Any upward force works against gravity,since they act in opposite directions.
Gravity and Upward force. If the upward force is greater than the weight caused by gravity than the plasticine will float.
The upward force is the reaction force of gravity; it is weight, which is mass x acceleration of gravity

No, gravity is a downward force.
The upward force would have to overcome gravity, so the force should be F > -mg. Since the upward force and gravity work in opposite direction you can disregard the mass of the object (they cancel: F(gravity) = F(upward) => mg = -m(g+x)) . Consequently the object's mass is irrelevant.
Airplanes do not "defy gravity", any more than you do when you walk upstairs. In both cases, an upward force is generated that is greater than the downward force of gravity on an object. Since the net force on the object is then upward, the object accelerates upward.
because if gravity
In low gravity- less effort and slow motion in upward and downward movement. in higher gravity - more effort and slow motion in upward movement and vice versa for downward movement.
