elastic collision: An elastic collision is a type of collision where kinetic energy and momentum are both conserved before and after impact. Objects bounce off each other without losing energy.
inelastic collision: An inelastic collision is a type of collision where kinetic energy is not conserved, but momentum is still conserved. Objects stick together or deform during the collision.
conservation of momentum: Conservation of momentum states that the total momentum of an isolated system remains constant before and after a collision. In other words, the combined momentum of all objects involved does not change.
