Potential (gravitational) energy is transformed into kinetic energy. So, for instance, if you lift an object, you're storing energy which will act on the object once you let it go (increasing velocity).

When an object falls, the potential energy gets converted to kinetic energy.
Some of its potential energy changes to kinetic energy.
-- the mass of the object -- the height through which it falls
Any object that is above ground level has potential energy. If the object falls down, the potential energy is converted to kinetic energy, i.e., the object will move at a certain speed.
If an object falls down, potential energy will be converted into kinetic energy (energy of movement). However, if an object drifts down slowly - say, a feather falling in air, or an object that falls down in water - the energy will be immediately converted to heat energy.

Increase.
When a photon of energy falls on an electron bound inside an atom, the electron absorbs the energy and is emitted from the atom.
For example, when an object falls, its potential energy decreases, but its kinetic energy increases, i.e., it falls faster and faster.
Generally, the higher an object goes, the higher its potential energy will be. This is because higher object will have more energy when it falls.
You are changing the object's gravitational potential energy. Gravitational potential energy is the energy due to position of the object above the Earth. This energy has the potential to be transformed into Kinetic Energy if the object falls.
