What causes wavy motion?

Wavy motion happens when something moves up and down or side to side in a repeating pattern, like the waves in the ocean.

Imagine you're on a swing at the park. When someone pushes you, you go forward, then backward, then forward again, that’s wavy motion. It's like a gentle dance between moving and stopping.

Pushes and pulls: Wavy motion often starts with something pushing or pulling. If you're on the swing, each push from your friend gives you more energy to go higher. The pull of gravity brings you back down, just like when you jump up and then land.

Once the motion starts, things can keep moving in a wave pattern because of energy. Think of a toy boat floating on water, if you dip your finger in the water, it makes ripples that move outwards. The energy from your finger keeps the waves going until they run out of strength.

So whether it's a swing, ocean waves, or even the sound of music, wavy motion is all about repeating up and down or side to side movement caused by pushes, pulls, or energy moving through something.
