Detailed explanation-1: -Characteristics of inelastic collision: Momentum is conserved in an inelastic collision. The complete amount of energy is preserved. The kinetic energy of the system is not preserved. An inelastic collision involves non-conservative forces.
Detailed explanation-2: -In physics, an inelastic collision occurs when some amount of kinetic energy of a colliding object/system is lost. The colliding particles stick together, and the maximum amount of kinetic energy is lost in a perfectly inelastic collision. In such cases, kinetic energy lost is used in bonding the two bodies together.
Detailed explanation-3: -Inelastic Collision When a collision occurs in an isolated system, the total momentum of the system of objects is conserved. Provided that there are no net external forces acting upon the objects, the momentum of all objects before the collision equals the momentum of all objects after the collision.
Detailed explanation-4: -A perfectly inelastic collision occurs when the maximum amount of kinetic energy of a system is lost. In a perfectly inelastic collision, i.e., a zero coefficient of restitution, the colliding particles stick together. In such a collision, kinetic energy is lost by bonding the two bodies together.
