Completely Inelastic Collision
A collision in which colliding bodies stick together after impact, moving as a single combined mass with maximum kinetic energy loss.
Governing formula
m1 v1 + m2 v2 = (m1 + m2) Vf
SI unit
kg·m/s, m/s
In depth
Sticking together minimizes final kinetic energy while strictly conserving linear momentum.
Examples in the real world
A clay ball thrown against a wall sticking to it, or a ballistic pendulum capturing a bullet.
