Archery and Energy By Hunter vilez


A Brief History of Archery

Although archery probably dates to the Stone Age (around 20,000 BC), the earliest people known to have used bows and arrows were the ancient Egyptians, who adopted archery at least 5,000 years ago for purposes of hunting and warfare. In China, archery dates back to the Shang dynasty (1766-1027 BC)

How does it work?


When you draw the bow you aren't stretching the string, you are compressing the bow into such a way that the limbs have forward tension. Then when you release the string it is puller forward by the limbs launching the arrow at your target.



When you pull the bow back the limbs compress getting more potential energy and the further back the arrow gets the more potential energy that has. When you release the bow the arrow flies forward with lots of potential energy and so do the limbs of the bow.



When you pull the bow back you are using mechanical energy to create elastic potential energy.

When you release the string that is a conversion from elastic potential energy to genetic energy.


NEWTONS FIRST LAW (law of inertia)

Newtons law of inertia simply states that an object in motion tends to stay in motion while an object at rest tends to stay at rest unless acted upon by an unbalanced force.

Example 1: An arrow hitting a target. The target is at rest and wants to stay at rest.


The bigger the arrow the larger the force and harder it hits the target and farther it goes.

NEWTONS THIRD LAW ( law of action/reaction )

Action: Pulling the bow back and releasing it

Reaction: The arrow flies in the direction you are aiming


The mass and velocity of your arrow determines your momentum

Once you have those things then you can calculate momentum by multiplying them.


When you Shoot an arrow there is air fiction acting upon that arrow.

When you release the string there is sliding friction on the whisker biscuit.


The more poundage you draw the more speed and velocity you will have. The lighter the arrow you have the more speed and velocity.
