Period of a Pendulum | Simple harmonic motion and rotational motion | AP Physics 1 | Khan Academy

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.

I love this teacher and respects what he is doing for us. When I will grow up, I will definitely donate a large sum to khan academy. Great work 👍 keep it up team

You are a very good teacher.

Saying that time period is indepedent of aplitude is incorrect, because during the derivation we started with assumption of "sin(theta) = theta" which yields the result, so for most of the aplitudes where sin(theta) is not equal to theta, the time period does depend upon the aplitude.
T = 2 . pi (l/g * (1+ alpha*alpha/16))^0.5, where alpha is the angle of rotation when pendulum's bob is lifted to max position

Great video, but pleaaaaaase get a mouth guard (puff guard) for the microphone. If you're listening with headphones you can hear the saliva. It's very unpleasant. Sorry. Just want to be honest.

Nice

About the period... isnt it wrong? For bigger oscilations, like 60º and 50º, oscilation periods do not match
