Describe equilibrium three ways: in words, with symbols, and as a labelled graph.
1. In words: Equilibrium is a state of balance where opposing forces are equal, allowing for no net change in the system.
2. With symbols: Σ F = 0 (where ΣF stands for summation of forces)
3. As a labelled graph:
|—————–>| Equilibrium Level <————|
