Review

• What is momentum?

  Quantity of motion (kg*m/s)
• J =

  Impulse
• J=∑F▵t=▵p


  Momentum Impulse Theorem
• Impulse?

  Force applied over a duration of time or change in momentum
• ∑p = ∑pʹ = m₁V₁ +m₂V₂ = m₁V₁ʹ +m₂V₂ʹ

  Conservation of Momentum
• Elastic?

  Collision that includes the complete transfer of momentum
• Inelastic?

  Collision that features two objects sticking together after the collision
• If you were to blow a dart through a tube and you were to cut the tube–making it smaller, what would be the impulse? (The same amount of force is used to blow the dart out)

  Less impulse
