Momentum & Impulse 2

3.2 Conservation of linear momentum
1. States
  • “In an isolated (closed) system, the total momentum of that system is constant.”
OR
  • When the net external force on a system is zero, the total momentum of that system is constant.”, Sp = constant,
OR
  •  The total of initial momentum = the total of final momentum
Spi = Spf
2. In 2-D Þ Spix = Spfx
                 Þ Spiy = Spfy

3. Type of collission


# Use to determine either it's elastic or inelastic collision
