For a mass in a uniform gravitational field the change in gravitational potential energy is:
DUg = mg Dh
Similarly, for a charge q moving a distance Dd parallel to the field, the change in electric potential energy is:
DUe = qE Dd
Whether it's an object with mass in a gravitational field, or a charged object in an electric field, when the object is released from rest it will accelerate in what direction?
What happens to the force on the object as the object falls in a uniform field?
