About Momentum Calculator
Momentum is an important physical quantity describing the state of motion of an object, equal to mass times velocity (p=mv). The law of conservation of momentum is one of the most fundamental conservation laws in physics. This tool helps physics students and teachers quickly calculate momentum, applicable to collision analysis, kinematics teaching, and more.
How to Use
- Enter the mass of the object (kg)
- Enter the velocity of the object (m/s)
- Click calculate to get the momentum (kg·m/s)

What is the law of conservation of momentum?
In the absence of external forces, the total momentum of a system remains constant. The vector sum of all momenta before a collision equals that after the collision. This is one of the most fundamental conservation laws in physics.
What is the relationship between impulse and momentum?
Impulse equals the change in momentum (I=Δp=F·Δt). The cumulative effect of a force applied over time equals the change in the object's momentum.
Is momentum a vector or scalar?
Momentum is a vector quantity with both magnitude and direction. Velocity direction must be considered in calculations. This calculator returns the magnitude (scalar value) of momentum.
