What can be said about the potential energy of a system in stable equilibrium?

Explanation

To determine what can be said about the potential energy of a system in stable equilibrium, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Equilibrium**:
- Equilibrium occurs when the net force acting on a system is zero. This means that the system is in a state where there is no net movement.

2. **Types of Equilibrium**:
