Oscillations: a quick overview. SHO: a box (mass m) on a spring (constant k)

Watch variables change

As the glider undergoes SHM, you can track changes in velocity and acceleration as the position changes between the classical turning points.

SHM phase, position, velocity, and acceleration

SHM can occur with various phase angles.

For a given phase we can examine position, velocity, and acceleration.

Damped oscillations

Energy in SHM

Vibrating moleculesTwo atoms in a molecule can be considered as two balls on a spring.

Torsion Pendulum

Forced (driven) oscillations and resonance

The Tacoma Narrows Bridge suffered spectacular structural failure after absorbing too much resonant energy

Waves

Transverse and longitudinal waves

Sinusoidal waves

Reflection and transmission

Superposition of waves (interference)

Diffraction of waves
