It's exactly the gravitational potential energy that the stone had, relative
to the ground, before it was dropped:
M G H = (9.8) x (the stone's mass) x (the height of the building) joules
The object initially has gravitational potential energy, which can be calculated with the formula GPE = mgh.As it falls, the potential energy is converted into kinetic energy.
During the fall, part of the kinetic energy may be converted into heat, by friction.
Once it hits the ground, most of the kinetic energy will be transformed into heat.
The stone initially has potential energy before being dropped; as it falls it is converted to kinetic energy as it speeds up; when it hits the ground it is converted to stain energy as it deforms; then it stops and energy is converted to heat energy; total energy is conserved.
Initially the stone has potential energy equal to mgh, where g is the acceleration due to gravity = 9.81 ms^-2. This energy is converted to kinetic energy of the stone.
The amount of force which gravity pulls down an object is called its weight.
mass of object *force of gravity
No. But the weight of that mass depends on the local gravity.
No. Those are two quite different forces. The Earth's gravity is caused by the amount of mass Earth has.No. Those are two quite different forces.

Gravity is a result of mass. Objects with twice the mass will have twice the gravity, assuming you are the same distance away.
No. as long as there is any amount of gravity. a ball can never go higher then where it was dropped if no force is added.
It depends on what percent it was dropped.
No. Mass is the amount of material in your body. Your weight is determined by gravity, and will increase as gravity increases, but the actual mass of your body is not affected by gravity.
It has a small amount of gravity, but still not proven.
Unless the top building is sufficiently high enough to lower the force of gravity by a substantial amount, you would weigh the same standing on top of a building as you would standing on any other non-accelerating (relative to the Earth) surface.
The gravity of the moon is 1/6 that of the earth.
The amount of force which gravity pulls down an object is called its weight.
The larger the planet is, the more amount of gravity you will get. The smaller the planet is, the less amount of gravity you will get.
The greater the mass, the stronger the gravity, but the distance does not affect the amount of gravity.
It's not it just has a unique amount of gravity. Even the moon has some gravity.
In two seconds of fall, the speed increases 19.6 meters (64.4 feet) per second. The magnitude of velocity increases by that amount, while the direction of velocity doesn't change.
