Law of Conservation of Momentum

• What is the Law of Conservation of Momentum?

  The total momentum of all objects in a closed system remains constant, regardless of any interaction within the system
• What is a Closed System?

  No particles in or out and no external forces
• Interaction also means...

  Collision
• What is this m₁V₁ + m₂V₂ = m₁V₁ʹ + m₂V₂ʹ

  After
• Collision that features two objects sticking together after the collision?

  Inelastic
• Collision that includes the complete transfer of momentum?

  Elastic
