These problems and exercises check for comprehension of Hooke’s law (stress & strain revisited); period & frequency in oscillations; simple harmonic motion (a special periodic motion); the simple pendulum; energy & the simple harmonic oscillator; uniform circular motion & simple harmonic motion; damped harmonic motion; forced oscillations & resonance; waves; superposition & interference; and energy in waves (intensity).
