ثبات (Stability) refers to the ability of a system or object to maintain its position or state despite external forces or changes. In physics, stability can describe how structures like buildings or bridges withstand loads and resist collapse. It is crucial in engineering to ensure safety and functionality. In psychology, ثبات can relate to emotional stability, which involves maintaining a balanced mood and coping effectively with stress. Individuals with high emotional stability tend to handle challenges better and experience fewer mood swings, contributing to overall well-being and resilience in life.
