David explains how a pendulum can be treated as a simple harmonic oscillator, and then explains what affects, as well as what does not affect, the period of a pendulum. Created by David SantoPietro .

- can u give me mathmatical reason why pendulum is not a shm in larger angles?If you study the derivation of the motion of the pendulum, at some point the angle is assumed to be small so that the angle (measued in radians) is...

- why does restoring force in a pendulum depend upon gravitywithout gravity, there would be no force to bring it back to its rest position. The bigger the gravitational field strength, the bigger will be the...

- Why the time period of the pendulum does not depend on the displacement of the angle theta?because the average speed of the pendulum goes up together with the distance that the pendulum has to travel.
- at 8:42 David explains about moment of inertia. but doesnt moment of inertia also depend on mass? I=...no, because bigger mass also means a bigger force. Objects all fall with the same acceleration, regardless of mass, right?

Watch on YouTube. This video tutorial lesson provides a wealth of details about the motion of a pendulum. Discussion topics include forces, free-body diagrams, force analysis with components, changes in speed and direction, position-time graphs, velocity-time graphs, changes in kinetic and potential energy, and the period-length relationship.
In this video, we’re going to learn about oscillating pendulums. We’ll see how pendulums can act as simple harmonic oscillators. And we’ll also see what factors do and do not affect a pendulum’s period. To get started, imagine that you are the keeper of a clock tower in a medieval town.
A pendulum behaves as a simple harmonic oscillator. Learn about the period of a pendulum, how it can be adjusted, and how it compares to a mass on a spring. Created by David SantoPietro.
