What is internal energy?

  1. Jan 16, 2014 #1
    Wikipedia says its the TOTAL energy contained by a thermodynamic system.

    But the textbook says
    Total energy = internal energy + kinetic energy + potential energy

    Strictly speaking, your textbook is the better, and more common, definition.
