Conjugation
The word "conjugation" is derived from a Latin word that means "to link together". In organic chemistry terms, it is used to describe the situation that occurs when π systems (e.g. double bonds) are "linked together". An "isolated" π (pi) system exists only between a single pair of adjacent atoms (e.g. C=C)
Kinetic energy
Kinetic energy is the energy associated with objects in motion. Potential energy is the type of energy associated with an object's potential to do work. Chemical energy is the type of energy released from the breakdown of chemical bonds and can be harnessed for metabolic processes.
Physics
Chemical physics is concerned with the application of the concepts and theories of physics to the analysis of chemical systems and their physical behaviour. While also at the interface between physics and chemistry, it is distinct from physical chemistry.
