ملخص الدرس

This lesson analyzes the mass–spring oscillator as the premier mechanical realization of Hooke's law and SHM. It derives the period formula T = 2π \sqrt{\frac{m}{k}} and frequency f = (\frac{1}{2}π) \sqrt{\frac{k}{m}}, proves that the period is independent of amplitude and gravity, tracks the continuous conversion between kinetic and elastic potential energy E = 0.5 k A^2, and highlights space applications like astronaut mass-measurement devices in microgravity.

• Hooke's Law gives the linear restoring force: F = -k x (stiffness k in \frac{N}{m}).
• Period of mass–spring oscillator: T = 2π \sqrt{\frac{m}{k}}; Frequency: f = (\frac{1}{2}π) \sqrt{\frac{k}{m}}.
• The period is completely independent of amplitude A and gravity g.
• Total mechanical energy is constant: E = 0.5 k A^2 = 0.5 m v^2 + 0.5 k x^2.
• Continuous cyclic transfer between kinetic energy and elastic potential energy.
• Practical applications: Automotive suspension springs, vibration isolators, and space mass meters.
