4 Models of Electric Phenomena: Electric Field and Forces Each source charge Q generates an Electric Field E Q Direction convention shown at right The net Electric Field is the sum of all the source fields Charge q, placed in an electric field E tot , experiences a force F elec on q =q E Q . For + test charge, force points in the same direction as field. For - test charge, force points in opposite direction of field Field, Forces, Potential Energy, and Potential
5 Models of Electric Phenomena: Field, Forces, Potential Energy, and Potential started in 7A Potential--started in 7B PE & V have similar PE F E V

8 Relationship between Potential Energy and Force 1 2 3 Potential Energy r - 0 Negative means decrease of PE with decreasing r
9 Relationship between Potential Energy and Force 1 2 3 Potential Energy r - 0 More slope closer to earth means F is greater there F = - PE / r , the - slope Force increases with greater slope
