States of Equilibrium – 9th Class Physics (Chapter 4: Turning Effect of Force)

When a body is slightly displaced from its position and then either returns to its original position, moves further away, or stays in the new position, it is said to be in one of three states of equilibrium:
---
The best of luck

🔹 1. Stable Equilibrium:

A body is in stable equilibrium if, after a slight displacement, it returns to its original position.
The centre of gravity rises when displaced and falls back when released.

The body regains balance.

Example: A cone resting on its base.
✅ Best for designing furniture, buildings, etc.

🔹 2. Unstable Equilibrium:

A body is in unstable equilibrium if, after a slight displacement, it continues to move away from its original position.
The centre of gravity lowers when displaced and keeps falling.

The body loses balance.

Example: A cone balanced on its tip.
⚠️ Easily disturbed and dangerous in structures.

🔹 3. Neutral Equilibrium:
A body is in neutral equilibrium if, after a slight displacement, it stays in its new position.
The centre of gravity remains at the same height.

No restoring or disturbing moment.

Example: A ball placed on a flat surface.
➖ No tendency to return or fall further.
