Graphs showing relationship between electric field strength and distance from charge Need to be able to calculate the net electric field strength at a specific point in space due to multiple charges (remember directions!) Parallel Plates Parallel plates can be used to accelerate/decelerate charged particles (therefore, there will be a change in kinetic energy) High electric potential energy is found at locations of repulsion and low electric potential energy is found at locations of attraction Parallel plates have a uniform electric field strength, therefore, cannot use the equation inside parallel plates In parallel plates, you can use any one of the following equations: , , or The voltage/electric potential between parallel plates does change Need to be able to calculate the electric potential difference/voltage between two points in a uniform electric field Work can be done against or work can be done by the electric field if the charged particle is moving parallel to the electric field. No work is done when a charged particle is moving perpendicular to the field. W = theorem, principle #3) ΔE (work-energy For charged particles initially moving horizontally through parallel plates (ie. perpendicular to the electric field) will follow a path similar to projectile motion trajectory as the charged particle starts to experience the electric force due to the parallel plates
