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

PhET simulation of Charges, Force and Electric Field lines

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.
