During inelastic collisions, momentum is conserved but not the kinetic energy.

\sum_{i=1}^{n}\vec{P_i} = \sum_{i=1}^{n}\vec{P'_i}

\sum_{i=1}^{n} {E_c}_i > \sum_{i=1}^{n} {E'_c}_i

This can be used for slamming or other wave-like loading (This model is reasonable when the impactor is relatively soft and the mass of impactor is larger than the mass of the node being impacted) (Context articles descriptions#Inelastic Impact of Composite Laminated Plate)

Perfectly Inelastic Collision

(aka "choc mous")

All material points have the same speed.

\forall i \in [1,n] \; \; \; \vec{V'_i} = \vec{V'}
