Arrow Weight Speed Formula:
| From: | To: |
The Arrow Weight Speed Formula calculates the speed of an arrow based on its weight and the base speed of the bow. This calculation helps archers understand how arrow weight affects arrow velocity and overall performance.
The calculator uses the Arrow Weight Speed Formula:
Where:
Explanation: The formula demonstrates the inverse relationship between arrow weight and speed - heavier arrows travel slower than lighter arrows when shot from the same bow.
Details: Understanding arrow speed is crucial for archers to optimize their equipment setup, improve accuracy, and achieve desired penetration power for different shooting scenarios and target types.
Tips: Enter the base speed of your bow in fps and the arrow weight in grains. Both values must be positive numbers greater than zero for accurate calculation.
Q1: Why is 350 used in the formula?
A: The number 350 represents a standard reference weight in grains that serves as a baseline for speed calculations in archery equipment.
Q2: What are typical arrow speed ranges?
A: Most modern compound bows produce arrow speeds between 250-350 fps, depending on draw weight, arrow weight, and bow efficiency.
Q3: How does arrow weight affect performance?
A: Heavier arrows provide better penetration and stability but travel slower, while lighter arrows fly faster but may sacrifice penetration and wind resistance.
Q4: Should I use this for hunting setup?
A: This calculator helps optimize your setup, but always test your actual equipment and consider factors like kinetic energy and momentum for hunting applications.
Q5: Are there limitations to this formula?
A: This formula provides an estimate and may not account for all variables such as bow efficiency, arrow spine, fletching, and environmental conditions.
