Because It is the vibration of the strings inside the piano that produces the sound of the piano.

A harpsicord is a keyboard type instrument which was the precurser of the piano,which works by plucking the strings, instead of striking them, like the piano. It means that hitting the key soft or hard always produces the same volume of sound, and makes it sound a little bland,lacking expression.

When you press down on the key of a piano, it causes a lever to move a hammer. The hammer then strikes a string that produces the sound.
it works by decreasing the distance between the hammers and the strings. So since the hammer has less room to travel when the soft pedal is pressed it can not build up as much speed therefore can not strike the string as hard which results in softer volume.
Soft sound means less intense. Intensity is directly proportional to the square of the amplitude. So amplitude will be less for soft sound.
If you play the piano softly it will sound soft. If you play it hard it will sound loud. It mainly depends on what piece you are playing. If you are playing a rock song then obviously it will have to be loud, but if it is a love song then most of the time you play it softly. Hoped this helped :-)
