The interpretation of Morse and Lennard-Jones energy profiles — •Grit Kalies¹ and Duong D. Do² — ¹HTW University of Applied Sciences, Dresden, Germany — ²The University of Queensland, Brisbane, Australia

In mechanics, the force is interpreted as dynamics. The second Newtonian law of motion, for instance, is interpreted to mean that the force changes the velocity or momentum. The third Newtonian axiom actio = reactio is interpreted as force = counter force. Based on the idea of force interaction, this is described today by four fundamental forces, which are attempted to be unified in vain. Force fields are assumed that have been quantized in quantum field theories to become carrier particles of the force. Force is considered the most important variable in physics [1]. In thermodynamics, a process in interpreted as dynamics. According to the first law of thermodynamics (energy conservation), only a process can change a state variable of a system, and any process takes time, whereby usually several state variables change simultaneously. To resolve the contradiction in the understanding of dynamics, we proposed a change in mechanics and quantum mechanics and introduced the momentum work and the momentum energy [2]. The current interpretation of energy profiles, such as the Morse and Lennard-Jones potentials, is replaced by a process-based interpretation that reveals the forms of energy released during the spontaneous formation of a bond.
