What is Amplitude in Physics with Example?

Amplitude in physics refers to the size or height of something that is moving or vibrating. It’s like how big a wave is or how far something moves back and forth.

Let’s imagine you’re swinging on a swing at the playground. The amplitude of your swing would be how high you go on each swing. If you swing really high, that means you have a large amplitude. But if you swing only a little bit, that means you have a small amplitude.

Another example is sound. When you listen to music, the amplitude of the sound waves determines how loud or soft the music is. If the amplitude is big, the music will be loud. If the amplitude is small, the music will be soft.

So, think of amplitude as the “bigness” or “loudness” of something that is moving or making a sound. It helps us understand how much energy is involved in the movement or vibration.
