Momentum Formula:
| From: | To: |
Momentum is a fundamental concept in physics that describes the quantity of motion an object has. For arrows, momentum determines the penetrating power and kinetic energy transfer to the target.
The calculator uses the momentum formula:
Where:
Explanation: Momentum is directly proportional to both mass and velocity. Increasing either mass or velocity will increase the arrow's momentum.
Details: Arrow momentum is crucial for hunting effectiveness as it determines the arrow's ability to penetrate through tissue, bone, and other barriers. Higher momentum arrows typically provide better penetration and more ethical kills.
Tips: Enter arrow mass in kilograms and velocity in meters per second. Both values must be positive numbers for accurate calculation.
Q1: Why is momentum important for arrow selection?
A: Momentum determines the arrow's penetrating power. Higher momentum arrows are better for hunting larger game as they maintain energy better through the target.
Q2: How does momentum differ from kinetic energy?
A: While kinetic energy (½mv²) emphasizes velocity, momentum (mv) emphasizes both mass and velocity equally. Momentum is better at predicting penetration, while kinetic energy predicts tissue damage.
Q3: What's a good momentum value for hunting?
A: For most big game hunting, momentum values between 0.5-0.8 kg·m/s are recommended, though specific requirements vary by game size and bow type.
Q4: How can I increase arrow momentum?
A: You can increase momentum by using heavier arrows (increasing mass) or by increasing arrow velocity through bow tuning or equipment upgrades.
Q5: Does arrow momentum affect accuracy?
A: Heavier arrows (higher momentum) are generally more stable and less affected by wind, but may have a more pronounced trajectory arc at longer distances.
