Momentum

• $p=$$mv$

  • Momentum (p) in kilograms metre per second (kg m/s)
  • Mass (m)in kilograms (kg)
  • Velocity (v) in metres per second (m/s)
• In a closed system, the total momentum before an event is equal to the total momentum after the event ; this is called conservation of momentum
• When a force acts on an object that is moving, or able to move, a change in momentum occurs
• $F=$$\frac{m\Delta v}{\Delta t}$

  • Force (F) in Newtons (N)
  • Change in momentum (m$\Delta$v) in kilograms metre per second (kg m/s)
  • Change in time (t) in seconds (s)
