SIMPLE PENDULUM, Time period, Frequency and Dependency| SIMPLE HARMONIC MOTION | Physics 12| Lecture 5 | National Book Foundation | Federal Board #FederalBoard #ModelTownHumak #EducationalChannel #siranjumteaches #nationalbookfoundation In this lecture, we explore the concept of the Simple Pendulum as a special case of Simple Harmonic Motion (SHM), based on the Class 12 Physics syllabus (National Book Foundation). You will learn how a simple pendulum consists of a heavy bob suspended by a light, inextensible string, and how its to-and-fro motion forms SHM when displaced through a small angle. Topics Covered: Derivation of Restoring Force: F = -mg sinθ Small Angle Approximation: sinθ ≈ θ Equation of SHM from Newton’s Second Law Expression of Time Period: T = 2π√(l/g) Frequency and Dependency on length (l) and gravity (g) Independence from bob’s mass 📘 This video is ideal for Class 12 students preparing for board exams and following the NBF Physics textbook. #SimplePendulum #Physics12 #SHMLecture #TimePeriodPendulum #FrequencySHM #FScPhysics #NationalBookFoundation #PhysicsUrduLecture Keywords: simple harmonic motion SHM physics 12 simple harmonic motion class 12 physics 12 chapter 17 simple harmonic motion federal board simple harmonic motion national book foundation free oscillations forced oscillations damped oscillations resonance in physics applications of SHM angular frequency frequency and angular frequency displacement in SHM amplitude and phase difference period and frequency oscillation and vibration restoring force and Hooke's Law F = -kx a = -w^2x velocity in SHM energy in SHM kinetic and potential energy SHM total energy in SHM energy exchange in SHM graphical representation of SHM displacement velocity acceleration graphs damping in oscillations light damping critical damping heavy damping graphs of damping car suspension system damping resonance examples free and forced oscillations examples standing waves and resonance rubens tube experiment chladni plates experiment acoustic levitation importance of critical damping resonance tuning examples resonance microwave oven resonance airplane wings resonance bridge collapse frequency response and sharpness sharpness of resonance curve quality factor in resonance natural frequency and resonance mechanical resonance spring mass system mass spring oscillator simple harmonic motion problems physics 12 NBF federal board physics 12 federal board physics chapter 17 nbf class 12 physics federal board new book physics national book foundation physics 12 12th class physics chapter 17 unit 17 simple harmonic motion shm mcqs class 12 shm short questions class 12 shm numerical problems phase and path difference forced vibration and damping underdamping overdamping critical damping driven oscillations and resonance real life applications of SHM
