The Physics 2 Tutor: Learning by Example DVD series covers thermodynamics, oscillations & waves in physics through step-by-step example problems. Emphasis is placed on giving students confidence in their skills by gradual repetition so that the skills learned are committed to long term memory. Lessons cover work, heat, and PV diagrams, including how work and heat are related, and how the Pressure-Volume (PV) diagrams can be used to illustrate this relationship.
