Force is defined by Newton's Second Law as F = m ยท a, where F is force, m is mass and a is acceleration. Net force is mathematically equal to the time rate of change of the momentum of the body on which it acts. Since momentum is a vector quantity (has both a magnitude and direction), force also is a vector quantity.",Mechanics,QUDT,http://qudt.org/vocab/quantity#Force,
