energyreturning
Energy returning refers to a concept found in physics and engineering where a system or material is able to store and then release a significant portion of the energy it has absorbed. This is in contrast to systems that dissipate energy, primarily as heat, during a process.
In a perfectly elastic collision, for example, energy is conserved and fully returned to the colliding objects.
The principle of energy returning is utilized in various applications. Sports equipment like running shoes and
