ملخص الدرس

This lesson lays the theoretical foundation for Simple Harmonic Motion (SHM) as the fundamental prototype of all mechanical vibrations. It defines amplitude, period, frequency, and angular frequency, derives the sinusoidal kinematic equations for displacement, velocity, and acceleration, and demonstrates that speed peaks at the equilibrium point while acceleration peaks at the turning points.

• Simple Harmonic Motion obeys the fundamental differential relationship a = -\omega^2 x.
• The restoring force and acceleration are always directed toward the central equilibrium position.
• Relationship between period, frequency, and angular frequency: f = \frac{1}{T} and \omega = 2πf = 2π/T.
• At equilibrium (x = 0): Speed is maximum (v_max = \omega A) and acceleration is zero (a = 0).
• At maximum displacement (x = \pm A): Speed is zero (v = 0) and acceleration is maximum (a_max = \omega^2 A).
