Answer:
Equilibrium is best defined as a state of physical balance.
Step-by-step explanation:
Physical balance is a term used to describe the situation in which the forces acting on a body on its internal and external side are equal. That is, the resulting force in this body is zero. In this case, we can say that this body is in a situation of equilibrium, where all things are in harmony and nothing is standing out or being ignored. That way all the factors that allow a body to function will function normally in a regulated and efficient way.
