Homework- Ex 6A, p. 188-196, Electric Fields
Definition of an Electric Field:
“Any region of space where a charge feels a force.”
Electric field lines are generated by charges. The closer the field lines are together, the stronger the electric field
Uniform Electric Field
E = V/d
E: Electric Field (Vm-1 or NC-1 depending on the context used)
Electric Force
Fe = Eq
Fe: Electrical Force (N)
q or Q: Charge (C)
Electrical Charge
Electrical Potential Energy
As the charge falls through the Electric Field, the electrical potential energy transforms into kinetic energy.
Ek = Ep
½ mv2 = Vq
