👉 In physics, a non-elastic collision is an interaction between two objects that does not result in significant change to either object's energy content or momentum. The concept of non-elasticity refers to the fact that such collisions do not involve significant changes in the kinetic energy of the objects involved, which means that there are no substantial changes in their velocity or direction. In other words, a collision between two particles is considered to be non-elastic if it does not result in appreciable change to either
