Simple Harmonic Motion (SHM) Quiz

Simple Harmonic Motion (SHM)

• The physical quantity that describes the state of oscillation of a particle in SHM is displacement, which indicates the particle's position relative to its equilibrium position.
• A phase of θ = 0° in SHM indicates the particle is at its maximum displacement in the positive direction, starting its motion back towards equilibrium.
• The SI unit of frequency is hertz (Hz), which represents one cycle per second.
• The equation for displacement (x) in simple harmonic motion is expressed as:
  [ x(t) = A \cos(\omega t + \phi) ]
  where A is the amplitude, ω is the angular frequency, t is time, and φ is the phase constant.
• A phase of θ = 270° signifies that the particle is at its maximum negative displacement, moving towards equilibrium and thus indicates a velocity change direction.
