Conservation of Energy and Momentum

When two objects interact in a heads-on collision, depending on the type of collision, momentum and energy are conserved, that is: Momentum of the system containing the two objects BEFORE the collision is equal to the Momentum of the system AFTER the collision. or, m1 × u1 + m2 × u2 = m1 × v1 + m2 × v2 where m1 and m2 are the masses of the two objects, u1 and u2 are the initial velocities BEFORE the collision, and v1 and v2 are the final velocities AFTER the collision. and, Kinetic Energy of the system containing the two objects BEFORE the collision is equal to the Kinetic Energy of the system AFTER the collision. or, dKE1 = dKE2 Momentum is always conserved. However, depending on the type of collision, either elastic or inelastic, the Kinetic energy isn't always conserved. If the collision was Elastic:
Both Kinetic energy AND Momentum are conserved, and both laws work simultaniously. If the collision was Inelastic:
Only momentum is conserved, Kinetic energy is dissipated into heat, sound, and material deformation, in this case, the law of conservation of Momentum is: m1 × u1 + m2 × u2 = (m1 + m2) × v Where m1 and m2 are the masses of the two objects, u1 and u2 are the velocities of the two objects before collision, and v is the Velocity of the final object formed from the joining of the two objects.
