Momentum: Mass in motion, impulse and the change in momentum. This free calculator solves for Momentum, impulse, collisions and shows every step.
Momentum is mass in motion, and total momentum is conserved in any collision with no external forces. Impulse — force applied over time — equals the change in momentum, which is why crumple zones and airbags (longer Δt) reduce the force in a crash.
A 1000 kg car at 20 m/s. p = 1000·20 = 20,000 kg·m/s. Stopping it in 2 s needs F = Δp/Δt = 10,000 N.
Vehicle crash analysis, rocket propulsion and recoil, billiards and sports impacts, particle physics.
Momentum uses the formula p = m·v. Mass in motion, impulse and the change in momentum.
Choose which variable to solve for, enter the values you know (in any supported unit), and the calculator substitutes them into p = m·v and shows every step of the working. It can solve for Momentum, impulse, collisions.
