Electric Fields: a vector quantity that relates the force exerted on a charge to the size of the charge magnitude measured in N/C direction of arrows: Charge of field Away from Positive charge toward negative charge Strength of field=space of line (close=stronger) Electric potential difference=Cause charges to move Grounding: Touching a body to earth to eliminate excess chrge law: relationship among electrical force charge and distance
 * Vocabulary**:

v=W on q
 * Formulas:**

q

W= Work (J) V= Potential Difference (V) q=Test charge (C)

F=Kqaqb

q2

F=Force K=electrical proportion constant= 9.0* 10^2 N*m^2/c^2 q=charge (c for coulomb) d=Distance (m)


 * Important:**
 * DO NOT PUT THE NEGATIVE IN THE FORMULA**
