Ecco una rottura:

* movimento: This refers to the kinetic energy of the particles within the substance. Think about molecules vibrating, rotating, and translating (moving from place to place).

* Energia immagazzinata: This refers to the potential energy stored in the bonds between particles.

Internal energy encompasses both of these forms of energy at the microscopic level. It's a fundamental concept in thermodynamics and plays a crucial role in understanding heat transfer, work, and various physical processes.
