What happens to the potential energy when one proton and one electron are brought close together?

The law of conservation of energy states that the total energy of an isolated system remains constant over time. This means that energy can't be created or destroyed, but can only be transformed from one form to another.  Here are some examples of conservation of energy: A pendulum swinging down A ball being thrown into the air A skier sliding down a hill A compressed spring launching a ball in a pinball game  The first kind of energy to be recognized was kinetic energy, which is energy from motion. Kinetic energy is determined by an object's mass and velocity.  Non-conservative forces... Show more

The law of conservation of energy states that the total energy of an isolated system remains constant over time. This means that energy can't be created or destroyed, but can only be transformed from one form to another. 

Here are some examples of conservation of energy:
A pendulum swinging down
A ball being thrown into the air
A skier sliding down a hill
A compressed spring launching a ball in a pinball game 

The first kind of energy to be recognized was kinetic energy, which is energy from motion. Kinetic energy is determined by an object's mass and velocity. 
Non-conservative forces are forces that cause energy to be converted into forms that cannot be easily regained. Examples of non-conservative forces include friction and air resistance.
