Answer: Equilibrium is a state in which opposing forces or influences are balanced, resulting in no net change in a system. It can refer to physical, chemical, or economic systems where opposing forces or factors interact in such a way that the system remains in a stable, unchanging state. In chemical equilibrium, for example, the forward and reverse reactions occur at the same rate, resulting in no net change in the concentrations of reactants and products. In mechanical equilibrium, an object is in a state of rest or uniform motion, with no net external force acting upon it.
