Learning Goal:
To understand the relationship and differences
between electric potential and electric potential
energy.
In this problem we will learn about the relationships
between electric force F, electric field
Ē,
potential
energy U, and electric potential V. To understand
these concepts, we will first study a system with
which you are already familiar: the uniform
gravitational field.
Part B
Now find the gravitational potential energy U (z) of the object when it is at an arbitrary height z. Take zero potential to be
at position z = 0. Keep in mind that the potential energy is a scalar, not a vector.
Express U (2) in terms of m, z, and g.
