Final answer:

Voltage and potential difference are related energy terms measured between points in space.


Explanation:

Voltage is the common term for potential difference. The relationship between voltage and energy is that voltage is the energy per unit charge at a point in space. Voltages are measured between two points because they are relative quantities. The units of volts and electron volts are related as they both measure energy per unit charge but differ in scale.
