What is an inelastic collision?
When two objects collide, becoming stuck together and internal kinetic energy is lost (but not really lost, it transfers to different forms of energy)
When two objects collide, becoming stuck together and internal kinetic energy is lost
When two objects don't collide, becoming stuck together and internal kinetic energy is lost (but not really lost, it transfers to different forms of energy)

Inelastic Collision
Elastic Collision
Perfectly Inelastic Collision
No collision occurred
