Momentum & Collision Calculator

Solve conservation of linear momentum (p = mv), impulse (J = FΔt), and elastic/inelastic 1D collisions.

Object 1

Mass (m₁ in kg)

Initial Velocity (u₁ in m/s)

Object 2

Mass (m₂ in kg)

Initial Velocity (u₂ in m/s)

Elastic Post-Collision Velocities

Perfect Inelastic (Stick Together)

v = +0.80 m/s

How to Use

Enter the mass and initial velocity.
Select Elastic & Inelastic Collisions to view the elastic post-collision velocities and perfect inelastic (stick together).
