Momentum Calculator

Calculate momentum from mass and velocity. Use the formula p = mv.

Inputs

Mass

Velocity

m/s

Tab to move between fields

Results

Momentum

100 kg·m/s

How to Use This Calculator

Enter object mass (kg) and velocity (m/s) -- use negative values for opposite direction.
Review momentum in kg*m/s using p = mv.
In a closed system, total momentum is conserved -- use before/after comparison for collision analysis.
Impulse (force x time) equals change in momentum -- key for sports, vehicle safety, and propulsion.

How the result changes with Mass

Mass	Momentum
100,000	1,000,000 kg·m/s
350,000	3,500,000 kg·m/s
650,000	6,500,000 kg·m/s
900,000	9,000,000 kg·m/s

What each input means

Mass: Mass of the object in kilograms.
Velocity: Velocity of the object in meters per second.
