ملخص الدرس

This lesson develops the theory, kinematics, and laboratory applications of the simple pendulum. It proves that restoring force linearity holds for small angular amplitudes (\theta \leq 10^{\circ}), derives the period formula T = 2π \sqrt{\frac{L}{g}}, establishes the principle of isochronism (independence of bob mass and small amplitude), and utilizes linear regression of T^2 versus L to determine local gravitational acceleration g experimentally.

• The simple pendulum executes SHM for small angles (sin \theta \approx \theta = \frac{x}{L}).
• Restoring force is the tangential component of weight: F = -mg sin \theta \approx -(\frac{mg}{L}) x.
• Period formula: T = 2π \sqrt{\frac{L}{g}}; Frequency: f = (\frac{1}{2}π) \sqrt{\frac{g}{L}}.
• The period is independent of bob mass, material, and small amplitude (Isochronism).
• The slope of a T^2 vs L graph equals 4π\frac{^2}{g}, allowing experimental measurement of g.
• The Foucault pendulum demonstrates Earth's rotation via plane-of-oscillation precession.
