Work done by electric force (source: fixed charges) on a test charge
... Electric forces are “conservative” - We can define a potential energy. When a + charge moves “down the field”, the electric force does work on it, increasing its kinetic energy (or putting energy elsewhere). When a + charge moves “up the field”, it either loses kinetic energy, or some other force mu ...

Work
... When is work done? • When we do work, it is done on an object. • If an object does not move through some displacement, then no work is done on that object. • In the same way, if there is no force acting on the object, there is no work. • Symbol: W • Units: Nm which is called a Joule ...
