The momentum of an object is

                      Momentum = (mass) times (speed) .

This simple formula shows that momentum is directly proportional
to speed.

Double the speed  ==>  double the momentum.

Triple the speed  ==>  triple the momentum.

Cut speed in half  ==>  cut momentum in half.

Reduce the speed  38.2%  ==>  reduce the momentum  38.2% .

etc.
