Lecture Topics

  • Energy conservation
  • Damped harmonic oscillators
  • Small angle approximation

Lecture Video: Damped Free Oscillators

A more realistic physical system, a damped oscillator, is introduced in this lecture. Prof. Lee shows the mathematical solutions actually match the behavior of physical systems. He also does an in-class demo to compare damped and undamped oscillators.
