Increasing the amplitude means that there is a larger distance to travel, but the restoring force also increases, which proportionally increases the acceleration. This means the mass can travel a greater distance at a greater speed.
These attributes cancel each other, so amplitude has no effect on period. The pendulum’s inertia resists the change in direction, but it’s also the source of the restoring force. As a result, the mass cancels out too.

From my limited understanding a swing is a pendulum.
Or, at least a good example of one.
"swing" swinging an action of what a pendulum can do.

I'm not totally grasping what you're ultimately trying to say.
Can you reword it and use a Taiji example?
I am not invested in swings or pendulums
I'm far more interested in Taiji.
Meaning I might have a better chance of understanding
if you tie it to a usage in Taiji
The swing was just a handy on the spot tool
to help them with a Taiji issue they were having.
And, for my education level,
the simpler the better
I'm very interested in understanding your message.

Then I went on a rant about Natural Resonance Frequency
(Hey, I am what I am, a Taiji evangelist).
I continue with, “Hey, Using small force at the right phase can create large amplitude vibrations if in phase with oscillation system, yada-yada…”
Under these conditions resonance occurs.
Resonance can cause the thing you’re adding the small force to--makes their structure fall apart, blah-blah blah…
I noticed his eyes started to glaze over again.
But, this time, I quickly pulled out my phone and showed them a short video of the Tacoma Bridge breaking apart from resonance.

You've never heard of this before ?
It's quite common, well known...maybe not..

Hey, Joe where you going?
I'm going to the market and then I going to go to _______
Want to come?

Being in resonance with another isnt in terms of mechanical motion, but rather in terms of being, thinking, feeling. Kung fu is something we experience in our bodies, where its clear and honest, but when kung fu goes up to our minds, it becomes a whole new entity and begins to sound like the "blind-men and the elephant" parable

I’m at a park. Someone new to Taiji asked me about Sticking.
They didn’t get the importance of sticking and listening.
Well…if you get good at sticking, you move in sync with your opponent & you use a small force to unbalance them.
They mention that since they were a young, they had trouble with timing in sports like baseball, basketball, etc.
