Various aspects of oscillations and waves, including oscillatory motion (amplitude, frequency, and velocity), traveling waves (types and properties, frequency, velocity, and wavelength), and sound (intensity vs. Distance and doppler effect). It also includes problem-solving exercises related to mass on a spring, pendulums, and pendulum clocks.

A mass oscillates on a spring. The acceleration of the mass is greatest when thevelocity isa) zero.b) greatest.c) half way between zero and its maximum velocity.d) None of the above.
