As little or as much as you want. The forcerequired to lift such a mass is calculated as mass x gravity. The pressure is simply the force divided by the area, so by having a large contact area, you can make the pressure approach zero.
The force acting on an object having a mass of 10Kg due to the Earth's gravitational field, what we commonly call gravity, would be 98.1Newton (Force=M*g).
However, gravitational force is present between any 2 bodies having mass and separated by a non-zero distance. That is, it's perfectly logical to speak of the gravitational force on an object of 10Kg mass due to another object of say, 20Kg mass separated by a distance of 100m (say).
anything over 10kg of direct pressure will do it
10 kg of mass weighs
-- 22.05 pounds (98.1 newtons) on earth
-- 3.6 pounds (16.2 newtons) on the moon
-- 8.38 pounds (37.3 newtons) on Mercury
If the object is on the earth, it weighs 98 newtons (22.05 pounds).
If it's on the moon, the same 10-kg object weighs 16 newtons (3.6 pounds).
On earth, this object's gravitational force is approximately 98.07N
The force of gravity on a mass of 10 kg at the Earth's surface is 98.0665 N.
F=mg =10kg*10m/s =100N.
10kg equates to 98.07N

The height is irrelevant. The energy required depends on the height; the force does not. The weight of an object, and therefore the force required to lift it, is mass x gravity - about 500 Newtons.The height is irrelevant. The energy required depends on the height; the force does not.

In that case, the mass will also be 10 kg.
The acceleration is 9.8 m/s2.
That would depend on the volume (density) of the 10kg object.

Both the 10kg stack of books and the 10kg piece of Styrofoam weigh the same amount, 10kg, because weight is a measure of the force due to gravity acting on an object's mass.

Uranus's mass is 8.6832*10kg
What is the mass of 1 sheep?
The airplane develops lift through the process of moving a mass of air over the wings at a sufficient rate ... the more mass per second, the more lift. The density of air is less at high altitudes, meaning any given volume has less mass than the same volume would have at lower altitude. In order to blow the required amount of mass (per second) over the wings and develop the required lift, more speed is required, hence a longer runway over which to accelerate.
As they are the same mass, theoretically it would take the same amount of energy. Assuming you are capable of lifting 10 Kg the concrete, being more compact, would be the easier task. Ten kilos of feathers would be quite bulky in comparison.
