  • Period of a mass on a spring (video) | Khan Academy
    Learn what affects the period of a mass on a spring (mass and spring constant), and what doesn't affect the period of a mass on a spring (amplitude and gravitational acceleration)
  • Definition of amplitude and period (video) | Khan Academy
    The maximum magnitude of displacement, so this amount right here, whatever that distance is here, is called the amplitude So we represent the amplitude with a capital A, and it's called the amplitude, and it's defined to be the maximum magnitude of displacement for that oscillator
  • Wave characteristics review (article) | Khan Academy
    The amplitude is a measure of the height of the crest To be specific, amplitude is defined to be the magnitude of the displacement from the equilibrium center line to the top of a crest
  • Wave properties (video) | Waves | Khan Academy
    Okay, what about the amplitude? Well, remember amplitude represents how far away, how high the peaks are, how low the valleys are, how much is the change from the equilibrium position
  • Sound properties: amplitude, period, frequency, wavelength
    The maximum displacement of the air molecule from its undisturbed position is called the amplitude Be careful The amplitude is not the length of the entire displacement It's only the maximum displacement measured from the equilibrium position Another key idea is the period of a sound wave
  • Period of a pendulum (video) | Oscillations | Khan Academy
    You're like, "Wait, don't these objects have farther to go now that you've pulled it back to a larger amplitude?" That's true, they'll both have farther to travel, but they'll be going faster now
  • Misleading line graphs (video) | 3rd quarter | Khan Academy
    The better thing to do, or the more genuine thing to do, or the more honest thing to do, would have actually been to plot them on the same graph Although if they did that, that wouldn't have painted a very good picture for Thrill Soda
  • Pendulums (video) | Oscillations | Khan Academy
    So, we've gotta assume we're in this small amplitude region where this mass on a string is acting like a simple harmonic oscillator And if that's true for small angles, the amplitude does not affect the period of a pendulum just like amplitude doesn't affect the period of a mass on a spring
