Momentum Calculator

Momentum p = mv combines mass and velocity into one quantity that governs collisions. Solve for momentum, mass, or velocity with unit conversion and full working.

How to interpret the result

Momentum measures 'how hard it is to stop' an object. A slow truck can carry more momentum than a fast bullet — that is why momentum, not just speed, decides collision outcomes, and why it is conserved when no outside force acts.

Assumptions

• Object treated as a point mass
• Velocity entered as speed along the direction of motion (magnitude)
• Non-relativistic speeds
