What is a bow and arrow and
how is it related to physics ?
- A bow is a fairly basic device that is constructed
from some kind of elastic material with two points and a
string running
between them. traditionally made from a flexible wood while
modern bows are typically made from a carbon fiber or metal.
- Archery involves physics far more than is immediately
evident, but the main purpose of the bow is to store the
mechanical energy
that is produced by the archer
and when triggered or released to transfer as much of the
potential energy into kinetic energy of the arrow.
- When the archer pulls the bow back the archers muscles
exert a force on the string that bends the limbs of the bow
backward. the amount of
force that the archers fingers
exert on the bows string when the bow is pulled is called the
draw weight. the elastic or or spring energy
of the bow is now potential
energy.
