16 - Oscillations
The simple plane pendulum Phase plane analysis, with and without
damping This applet allows the user to set the damping and
initial angle and angular velocity. It then animates the motion
of the pendulum and plots its trajectory in the phase plane.
The damped harmonic oscillator Position, velocity, and energy
versus time This applet allows the user to set the damping
coefficient and initial position and velocity. It then animates
the motion of the oscillator and plots its position,velocity, and
energy as functions of time.
Coupled oscillations Normal modes and more general motions The
user sets the initial positions of the bodies either by sliding
them along the track or by clicking on one of the light blue bars
in the frequency spectrum, which puts the system into its
corresponding normal mode. The frequency spectrum of the
resulting motion is shown by the dark blue bars. The number of
bodies can be varied from 1 to 7.
