Resonance

Real World Example

Imagine trying to push someone on a swing; if you push at the right moment, they'll go higher and higher. This is similar to resonance, where an object increases its vibration amplitude when another object vibrates at the same frequency. Just as timing your pushes with the swing's natural rhythm makes it soar higher, when two objects share the same vibration frequency, one can amplify the other's motion, leading to increased energy and movement.
