how are balance and stability different concepts?

Balance and stability are related but distinct concepts. Balance is the ability to maintain the body's center of gravity or equilibrium over its base of support, typically without movement or disturbance. It's about keeping upright and steady, usually in a static position or during simple movements. Stability, on the other hand, is the ability to control the body during movement or after a disturbance, enabling a person or object to return to or maintain a desired position despite external forces or disruptions. Stability involves strength, control, and positioning, especially under dynamic conditions where forces may be unbalanced. In summary, balance is about maintaining equilibrium in a given posture or task, while stability is more about managing forces and maintaining control during movement or external challenges. Stability is a dynamic state that supports balance, especially in real-life activities involving motion or impact.
