Analyze electric force with this simulation. Point Charge Forces in One-Dimension model investigates the electric force that one charged particle exerts on another. It is a very simple representation that promotes understanding of Coulomb's Law in three ways: First, students can set the amount of charge on each particle and view vector arrows showing the force on each particle. Second, particle 2 can be dragged left or right to sample the force at various locations. Third, users can click to see a graph that shows electric force as a function of position. The numerical value of each force is shown in a table at the bottom.
