Momentum

• All moving objects have momentum
• Momentum is a measure of how difficult it is to stop a moving object
• Bigger mass/faster movement leads to more momentum
• Momentum = mass x velocity

  Momentum - p

  Mass - m

  Velocity - v
• Mass is measured in kilograms (kg)
• Velocity is measured in metres per second (m/s)
• Momentum is measured in kilogram metres per second (kg m/s)
• A 5400 kg elephant charging at 11 m/s.

  What is the momentum?

  p = mv

  p = 5400 x 11

  p = 59400 kg m/s
