Momentum Calculator

p=mv, impulse and impact force

Quick Answer

Momentum Calculator: p=mv, impulse and impact force. Momentum Calculator uses standard science & engineering formulas to compute accurate results instantly.

m (kg)

v (m/s)

p (kg·m/s)

Momentum

700.0 kg·m/s

Steps

1p = m × v = 70 × 10 = 700.0 kg·m/s

Typical momenta

Object	Speed (mass)	p
子弹 (9mm, 8g)	360 m/s	2.88 kg·m/s
棒球投手速球	44 m/s (160g)	7.0 kg·m/s
短跑运动员	10 m/s (70kg)	700 kg·m/s
小汽车市区	14 m/s (1500kg)	21,000 kg·m/s
高铁列车	83 m/s (450t)	3.7×10⁷ kg·m/s

💡 p = mv; total momentum is conserved in ALL collisions (energy is not). Impulse F·Δt = Δp — that's why airbags extend collision time to cut force, and why you bend your knees landing a jump. In perfectly inelastic collisions (objects stick), KE loss is maximal.
