What is amplitude?

Amplitude is how big or strong something is when it moves up and down.

Imagine you're on a swing. When you go really high, that’s amplitude, it's like the swing's biggest stretch. If you only go a little way up, that’s a smaller amplitude. It's all about how far you go from the middle point to the top.

Like a Bouncing Ball

Think of a ball bouncing on the floor. When it bounces really high, that’s a big amplitude. If it barely lifts off the ground, that’s a small amplitude. The higher it goes, the more energy it has, just like how you feel when you swing higher and higher!

A Wave's Height

Now imagine water waves in the ocean. The taller the wave, the bigger the amplitude. If you're on a boat, a big amplitude means you'll go up and down more, kind of like being on a really bouncy ride!

Examples

  1. A wave in the ocean has a certain height, that's its amplitude. A bigger wave means more energy!
  2. When you speak, your voice creates sound waves with different amplitudes. Speaking louder increases the amplitude.
  3. Imagine a bouncing ball: the higher it goes, the greater the amplitude of its bounce.
