Question

what do we call the amount of energy gained or lost per unit of electric charge as that charge moves between two points?

Answer 1

As the charge moves between two points it either gains or loses potential electric energy known as Electric Potential or Voltage.

So the work done on moving a single unit of charge between two points is known as Voltage. Where

1 Volt = 1joule/ 1 coulomb

So the work done on the charge gets stored in on the point of storage which has the potential to do same work. So it means it gains or loses potential energy. If charge is being moved to similar points it gains potential energy or Voltage, if it is moved to opposite points it losses potential or Voltage.
