Study Notes

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.
