1. What is an Omni Arrow Speed Calculator?

Definition: This calculator determines the speed of an arrow based on its kinetic energy and mass using the physics formula for kinetic energy.

Purpose: It helps archers and bowhunters understand the velocity of their arrows for better accuracy and performance tuning.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( V \) — Arrow speed (meters per second)
• \( E \) — Kinetic energy (joules)
• \( m \) — Arrow mass (kilograms)

Explanation: The formula derives from the kinetic energy equation, solving for velocity when energy and mass are known.

3. Importance of Arrow Speed Calculation

Details: Knowing arrow speed helps with trajectory prediction, kinetic energy at impact, and bow tuning for optimal performance.

4. Using the Calculator

Tips: Enter the kinetic energy in joules and arrow mass in kilograms. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: How do I measure arrow kinetic energy?
A: Use a chronograph to measure speed, then calculate energy with \( E = \frac{1}{2}mv^2 \).

Q2: What's a typical arrow mass?
A: Most arrows range from 0.02 to 0.04 kg (20-40 grams), depending on materials and purpose.

Q3: Why use meters/second instead of fps?
A: The formula uses SI units; you can convert m/s to fps by multiplying by 3.281.

Q4: Does this account for air resistance?
A: No, this calculates initial speed at launch. Actual speed downrange will be less due to drag.

Q5: What's a good speed for hunting?
A: Most hunters aim for at least 60 m/s (200 fps) with sufficient kinetic energy for ethical kills.
