16 wrz 2024 · The internal energy of a substance is defined as: The sum of the randomly distributed kinetic and potential energies of the particles in a body. This means internal energy is the total of all the kinetic energies plus the total of all of the potential energies. The symbol for internal energy is U, with units of joules (J)

All molecules in a substance possess both kinetic and potential energies. The internal energy of a system can increase by: Doing work on it
Definition and Significance: Internal energy is the sum of all forms of energy within a system, fundamentally linked to the motion and interaction of particles. It's a key concept in understanding how energy is stored, transferred, and transformed in physical systems. Components of Internal Energy:
AQA Physics A-level. Section 6.2: Thermal Physics . Notes. 3.6.2 Thermal physics. 3.6.2.1 - Thermal energy transfer. The internal energy of a body is equal to the sum of all of the kinetic energies and potential energies of all its particles. The kinetic and potential energies of a body are randomly distributed.
