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 oscillations and simple harmonic motion, as well as how this motion can be modeled by a sinusoid. Grades 9-12. 55 minutes on DVD.
