1. Total Momentum: The total momentum of the system remains the same before and after the collision. This means that the sum of the momenta of all objects involved in the collision remains constant.
2. Energy Conservation: In inelastic collisions, kinetic energy is usually not conserved. Instead, a part of the initial kinetic energy of the colliding objects is transformed into other forms of energy, such as thermal energy (heat) or internal energy. Energy conservation law still holds, but now includes internal energy and any work done by non-conservative forces in addition to kinetic energy.
