Conservation of Momentum Calculator

Calculate momentum conservation in two-body collisions

Solve For:

Mass (kg):

Initial Velocity (m/s):

Final Velocity (m/s):

Mass (kg):

Initial Velocity (m/s):

Final Velocity (m/s):

m1*v1i + m2*v2i = m1*v1f + m2*v2f

Total momentum is conserved in all collisions.

Note: Use negative velocities for opposite directions.
