Elastic Collision: An elastic collision occurs when objects collide and bounce off each other without any permanent deformation or energy loss.
Inelastic Collision: An inelastic collision occurs when objects collide and stick together after impact, resulting in deformation or energy loss.
Conservation of Momentum: Conservation of momentum states that for any closed system, such as colliding objects, the total momentum before and after a collision remains constant as long as no external forces are present.
