Calculate momentum, impulse, elastic and inelastic collisions
Perfectly inelastic collision where objects stick together. Momentum conserved, kinetic energy lost.
This free momentum calculator physics tool helps students and educators solve momentum, impulse, and collision problems with detailed step-by-step solutions.
Momentum (p) is the product of an object mass and velocity: p = mv. It is a vector quantity with both magnitude and direction. The SI unit is kg m/s.
Impulse (J) is the change in momentum of an object. It equals force multiplied by time: J = Ft = change in p
Elastic Collision: Both momentum AND kinetic energy are conserved. Objects bounce off each other. Example: billiard balls.
Inelastic Collision: Only momentum is conserved. Some kinetic energy is lost to heat, sound, or deformation. Example: car crashes.
Perfectly Inelastic: Objects stick together after collision. Maximum kinetic energy loss while conserving momentum.
