In which of the following collisions is momentum conserved? Elastic Explosion Inelastic

Momentum is conserved in all types of collisions, including elastic, explosion, and inelastic collisions. This is due to the law of conservation of momentum, which states that the total momentum of a closed system remains constant if no external forces act on it. In an elastic collision, both momentum and kinetic energy are conserved. In an explosion, the momentum is conserved, but the kinetic energy is not necessarily conserved. In an inelastic collision, momentum is conserved, but kinetic energy is not necessarily conserved.
