Chapter 14
  • Oscillations

Section 14-1 Simple Harmonic Motion A simple
harmonic oscillator is any system that
oscillates. An example of this is a mass on the
end of a spring. F is a linear restoring force.

The frequency and period of the simple harmonic
oscillator are independent of the amplitude.

The Simple Pendulum
15
The speed is not uniform in a simple pendulum.
The speed is greatest near the bottom of its
swing. The reason why the period is independent
of amplitude is because the speed makes up for
the difference in amplitude.

Pendulum in an accelerated reference frame The
tilt of a pendulum in an accelerated reference
frame forms the basis of modern accelerometers.
