How do capacitors work?
The capacitance of a capacitor is a bit like the size of a bucket: the bigger the bucket, the more water it can store; the bigger the capacitance, the more electricity a capacitor can store. There are three ways to increase the capacitance of a capacitor. One is to increase the size of the plates. Another is to move the plates closer together.

The electric force is one example of a force varying with distance. The potential energy stored in the field of two point charges will change as you increase the distance between the charges from r 1 to r 2.
