Reversibility can refer to:

  • Reversible dynamics, a mathematical dynamical system, or physical laws of motion, for which time-reversed dynamics are well defined
  • Reversible computing, logical reversibility of a computation - a computational step for which a well-defined inverse exists
  • Reversible process (thermodynamics), a process or cycle such that the net change at each stage in the combined entropy of the system and its surroundings is zero
  • Reversible reaction, a chemical reaction for which the position of the chemical equilibrium is very sensitive to the imposed physical conditions; so the reaction can be made to run either forwards or in reverse by changing those conditions
  • Reversible error, a legal mistake invalidating a trial
  • Reversible garment, a garment that can be worn two ways
  • Piaget's theory of cognitive development, in which mental reversibility is part of the concrete operational stage, the understanding that numbers and objects can change and then return to their original state
  • Tesla principle, now known as a reversible process in engineering, a process of a system such that a net reverse in operation will accomplish the converse of the original function
