Inside the piano, the hammer waits…
When you press a piano key, you’re actually setting off a tiny chain reaction of physics in motion. The key works like a lever. Your finger’s force pushes it down, which makes the small hammer fly up toward the string. Newton’s laws of motion explain this: your push gives the hammer acceleration, and when it hits the string, that kinetic energy turns into vibrations.
Those vibrations create sound waves, which we hear as musical notes. The faster and harder you press, the more energy and the louder the sound. The hammer’s soft felt helps control the tone, turning raw energy into the warm, rich sound of a piano.
