Analyze the following statements regarding the fundamental characteristics of Simple Harmonic Motion (SHM).
I. SHM is a specific type of periodic motion where the restoring force is directly proportional to the displacement from the mean position.
II. The direction of the restoring force is always towards the mean position, opposite to the displacement.
III. The acceleration of a particle in SHM is constant in magnitude and direction throughout the motion.
IV. The time period of SHM is independent of the amplitude of oscillation (for small amplitudes in case of a pendulum).
V. The velocity of the particle is maximum at the extreme positions and minimum at the mean position.
