Piano physics
My topic is about how physics or pressure affects the sound of the piano. Pressure is the amount of force over the area that the force is applied or P=F/A. Force is measured in newtons, which is not the same as pressure which is newtons per square meter, or pascals. (Pa). A small person can make a loud sound on the piano because of how much pressure is applied to the keys. An example of how pressure and weight are different is, if your lightly pushing down on the keys of the piano the sound will be quiet and peaceful. If you push the keys harder the sound is louder and more clear.
The piano creates sound when you push on the keys, that is because each key is attached to a small hammer that hits a wire inside the piano. The different sounds are caused by the length and size of each wire, affecting the sound as well as the volume. The wire length affects the sound difference because the sound waves are much greater on a thicker wire than a smaller one. When you lift the piano key back up the sound stops because of a thing called a damper. A damper is a thing that is forced up into the air off the wire when you push the keys activating the hammer. When you lift the key again, causing the hammer to leave the wire the damper falls back across that wire muffling the sound.
