• momentum


  the force or speed with which something moves
• momentum (kg m/s) =

  mass (kg) x velocity (m/s)
• momentum formula


  p=mv
• momentum formula triangle

  
• conservation of momentum


  the total momentum of a system of objects does not change, as long as no outside forces are acting on that system
• if in a crash a moving car hits a parked car and they start moving together, why would they be travelling at a lower velocity?

  due to the conservation of momentum
• you can use the conservation of momentum to calculate...

  velocities or masses
• why is momentum a vector quantity?

  because velocity has magnitude and direction
• force causes a ... in momentum

  change
• force (N) =


  change in momentum (kg m/s) / time (s)
• change in momentum formula triangle

  
• change in momentum formula

  F=mΔv/t
• the force causing the change in momentum is ... to the rate of change of momentum


  equal
• a larger force means a ... change in momentum
