What are the physics behind a crossbow?

Answer:
A taut string is pulled back and released to get an arrow to fly.
Doing work to pull the string back stores energy in the string as elastic energy. When the string is released, it converts its energy into kinetic energy and transfers this via a collision to the bow.
