Momentum 1.6

• Equation for momentum

  mass x velocity
• Unit for velocity

  m/s
• Unit for mass

  kg
• Momentum depends on two things: mass and velocity.
• What is the law of conservation of momentum?

  sum of total momentum before collision is equal to sum of total momentum after collision if there are no external forces
• What are the two scenarios of momentum?

  1. objects stick together
  2. objects move at different speeds
• Equation for object sticking together after Collision (momentum)

  (M1xv1)+(m2xv2)=(m1+m2)v
• Equation for objects move at different speeds

  (M1xv1)+(m2xv2)=(m1xv3)+(m2xv4)
