Momentum & Impulse Calculator

Calculate momentum (p = m·v) and impulse (J = F·Δt). Impulse equals change in momentum.

Mass in kilograms.
Velocity in m/s (can be negative).
Force in Newtons.
Duration of applied force.
Momentum: p = m·v
Impulse: J = F·Δt
J = Δp
SI units assumed.
A large force over a short time can produce the same impulse as a small force over a long time.
Example: airbags increase collision time.
