An oatmeal cookie is dropped on the floor. Is this an inelastic collision? Why or why not? It is because the cookie and floor can be considered one object. It is because the cookie and floor are stuck together. It is not because there is not momentum involved. It is not because the cookie and floor do not move away together as a unit.
