momentum

• Momentum equation:

  momentum = mass × velocity

  p = m v

  momentum, p, in kilograms metre per second, kg m/s

  mass, m, in kilograms, kg

  velocity, v, in metres per second, m/s
• conservation of momentum

  In a closed system, the total momentum before an event is equal to

  the total momentum after the event
• Momentum (kg m/s) = mass (kg) x velocity (m/s)
