1. What is the Recurve Arrow Speed Formula?

The Recurve Arrow Speed Formula estimates arrow velocity from draw weight and base speed. It provides a simple calculation for archers to predict arrow performance with different bow setups.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Draw_{r\_s} \) — Draw weight in pounds
• \( Base_{r\_s} \) — Base speed in fps (feet per second)
• \( Speed_{rec\_a} \) — Calculated arrow speed in fps

Explanation: The formula accounts for the linear relationship between draw weight and arrow velocity, with a base speed constant that varies by bow design.

3. Importance of Arrow Speed Calculation

Details: Accurate arrow speed estimation is crucial for trajectory prediction, kinetic energy calculation, and determining effective hunting ranges.

4. Using the Calculator

Tips: Enter draw weight in pounds and base speed in fps. Both values must be positive numbers for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this formula?
A: This provides a general estimation. Actual arrow speed can vary based on arrow weight, bow efficiency, and archer technique.

Q2: What is a typical base speed value?
A: Base speed typically ranges from 100-150 fps depending on bow design and setup.

Q3: Does arrow weight affect speed?
A: Yes, heavier arrows will travel slower than lighter arrows with the same bow setup.

Q4: How does draw length affect arrow speed?
A: Longer draw lengths generally produce higher arrow speeds as more energy is stored in the bow.

Q5: Should I use this for competition planning?
A: While helpful for estimation, professional archers should use chronographs for precise speed measurements.
