1. When we have two charged particles interacting, there is a difference between potential energy and electric potential. • True • False

2. The units on electric potential energy are • Volts • Coulombs • Joules • Newtons

3. Assuming that we have a electric field between a positive plate and a negative plate and that the field does positive work on a particle, the electric potential energy of the particle • Increases • Decreases • Increases or decreases depending upon the sign of the charge of the particle

4. The units on electric potential are • Volts • Coulombs • Joules • Newtons

5. Points in an electric field where a particle will have the same electric potential energy are found along • The electric field lines • The equipotential surfaces/lines • Does not apply, no two locations will ever have the same electric potential energy.

6. It is possible for a particle to move in an electric field without the electric potential energy changing. • True • False • The question makes no sense.
