Momentum

• Momentum


  The product of mass and velocity
• Momentum

  A vector quantity
• Momentum

  Momentum = Mass x Velocity
• Momentum is a vector quantity
• A force acts on an object that is moving

  There is a change in Momentum
• Change in Momentum

  Measured in (kgm/s)
• Crumple Zones

  Areas of a car that crumple on impact
• Crumple Zones


  These features decrease the rate of change of Momentum reducing the impact
• Force


  Force = Mass x Acceleration
• Conservation of Momentum

  Total Momentum before an event = Total Momentum after the event
• Momentum is conserved in collisions and explosions
• Conservation of Momentum


  Can be used to calculate Mass, velocity or Momentum
• Principle of conservation of Momentum


  Can be used to calculate Mass, velocity or Momentum
