Revision

Revision. Previous lecture was about Harmonic Oscillator. Simple Harmonic Oscillator. In classical mechanics, a harmonic oscillator is a system that, when displaced from its equilibrium position, experiences a restoring force, F , proportional to the displacement, :

Dissipative Force

Dissipative Force. Generalized force came from a transformation. Jacobian transformation Not a constraint Conservative forces were separated in the Lagrangian. Non-Potential Force. Velocity Dependent. A function M may exist that still permits a Lagrangian.
