In our studies of the force between electric charges, we have constructed an equation to tell us how much force one charge exerts on a second. (If there are many charges exerting forces, we have to add up all those forces to find out the electric force a given charge feels.) One way of writing this equation is in symbols:
A second way would be to use words representing the ideas involved rather than symbols in the equation:
