Arrow Speed Formula
Formula
v = √(2KE / m)
or from bow:
KE = η × F × d
Where:
- • v = arrow speed (m/s)
- • KE = kinetic energy (J)
- • m = arrow mass (kg)
- • F = draw weight (N)
- • d = draw length (m)
- • η = efficiency (~0.8)
Typical Arrow Speeds
- • Target archery: 40-50 m/s
- • Hunting: 50-70 m/s
- • Compound bow: 60-90 m/s
- • Crossbow: 80-120 m/s
