Okay, if there's a cup on the table, and it's knocked off, and it falls to the ground, it explodes upon hitting the ground because that's energy being released. The higher the table is, the greater the explosion and shattering of the cup. So, this is gravitionial potential energy, which increases with elevation, or distance from the center of the attractive mass.
Likewise, if I have a paper cup, and I light it with a match, it bursts into flames, because the hydrocarbons in the cup is being oxidized. If the cup was made out of gunpowder, the burst is more vigorous. This is chemical potential, and some chemicals have a stronger reaction when mixed with the right reactants than others. Flouride is extremely reactive, and "burning" it with hydrogen gas to produce hydrogen flouride is powerful; thus there's a high chemical potential with these elements.

Uses Of Gravitational Potential Energy

A weight on a shelf. If it falls off it releases potential energy on the way to the ground. That is gravitational potential energy.
An example of chemical potential energy would be found in a battery,.

Life example like real world? Well.
Gravitational potential energy...
A roller coaster peaked at the top of a hill not moving but one push gets it on its way. (It has the POTENTIAL to go really fast and have high kinetic energy if gravity pulls it down.)
A skydiver works well too sitting in the plane ready to jump.
Chemical potential energy...
Hydrogen. If near a heat source, the substance excites and explodes releasing its stored potential energy. Like new age hydrogen car. It has energy stored for potential uses and once mixed with oxygen, it combusts releasing the stored energy making H20 as a by-product.
