How to Use This Calculator

Enter mass 1 (kg) and mass 2 (kg) for the two colliding objects.
Enter initial velocity of object 1 (m/s) and initial velocity of object 2 (m/s) — use negative for leftward.
Read final velocities of both objects after the elastic collision.
Verify conservation: total kinetic energy before should equal total kinetic energy after (J).
Review kinetic energy transferred (J) and momentum before and after to confirm conservation laws.
