Draw Weight to Speed Calculator

Calculate Arrow Speed



Formula

To calculate the Speed of the Arrow (v):

\[ v = \sqrt{\frac{2W}{m}} \]

Draw Weight Definition

Draw weight is the amount of force required to draw a bowstring to a specific distance, typically measured in newtons (N) or pounds (lbs). It is a critical factor in archery as it influences the speed and distance an arrow can travel. Higher draw weights generally result in faster arrow speeds and greater impact force, making it essential for archers to choose a draw weight that matches their strength and skill level. Properly matching the draw weight to the archer ensures better accuracy and performance in shooting.

Example Calculation 1

Let's assume the following values:

Using the formula:

\[ v = \sqrt{\frac{2 \times 500}{0.05}} \approx 141.42 \text{ m/s} \]

The speed of the arrow is approximately 141.42 m/s.

Example Calculation 2

Let's assume the following values:

Using the formula:

\[ v = \sqrt{\frac{2 \times 300}{0.03}} \approx 141.42 \text{ m/s} \]

The speed of the arrow is approximately 141.42 m/s.
