What type of equilibrium is exhibited by a perfectly balanced seesaw when it remains at rest?
21. What type of equilibrium is exhibited by a perfectly balanced seesaw when it remains at rest?
- Stable equilibrium
- Neutral equilibrium
- Unstable equilibrium
- Dynamic equilibrium
Answer
The correct answer is: A) Stable equilibrium
Explanation
When a system is in stable equilibrium, it returns to its beginning position after being pushed slightly. When one end of a perfectly balanced seesaw is slightly raised the system usually returns to its original equilibrium.
