Sense Of Balance , which maintains physical balance in humans and animals
In the physical sciences
Thermodynamic Equilibrium , when internal processes of a system cause no overall change in temperature or pressure
Dynamic Equilibrium , when two reversible processes (in thermodynamics) occur at the same rate
Chemical Equilibrium , when a chemical reaction proceeds at the same rate as its reverse reaction, with no change in the amount of each compound
Mechanical Equilibrium , when the sum of the forces and moments on each particle of a system is zero
Quasistatic Equilibrium , when internal processes change gradually from one equilibrium state to the next
In biological science
Punctuated Equilibrium , a part of evolutionary theory that states that speciation occurs relatively quickly with long periods of little change in between.
