In simple harmonic motion (SHM), the maximum amplitude refers to the maximum displacement of the object from its equilibrium position. The motion of the object is considered SHM as long as the displacement is proportional to the restoring force and follows a sinusoidal pattern.
In SHM, the maximum amplitude can be any positive value. It is determined by the initial conditions of the system or the setup of the experiment. The maximum amplitude represents the maximum distance the object oscillates from its equilibrium position.
The equation of motion for an object undergoing SHM can be represented as:
x(t) = A * cos(ωt + φ)
where: x(t) is the displacement from equilibrium at time t, A is the amplitude (maximum displacement), ω is the angular frequency (related to the period of the motion), and φ is the phase constant (initial phase angle).
As long as the motion of the block follows this equation and satisfies the conditions of SHM, the maximum amplitude can be any positive value, depending on the system or experiment.
